Subject: wireless: hostap, fix oops due to early probing interrupt

BugLink: https://bugs.launchpad.net/ubuntu/+bug/254837

Spurious shared interrupts or early probing interrupts can cause the
hostap interrupt handler to oops before the driver has fully configured
the IO base port addresses. In some cases the oops can be because
the hardware shares an interrupt line, on other cases it is due to a
race condition between probing for the hardware and configuring
the IO base port. The latter occurs because the probing is required to
determin the hardware port address which is only determined when the probe
can interrupt the hardware (catch 22).

This patch catches this pre-configured condition to avoid the oops.

AR9170 has the bad habit of choking when traffic builds up.
Tests have shown that this can partially be attributed to
a huge buildup of backlogged frames.

The flags in question were once useful for debugging.
Time has passed and now they do nothing more than
duplicating txinfo->flags.

This patch aggregates a bunch of small random changes
that won't fit really anywhere else properly.

1. move tid-locating macro into a separate function.

2. remove redundant NULL check.

3. add modulation mask definition

to use the same. Otherwise problems with wakeup might get unnoticed.

Subject: iwlwifi: add continuous uCode event log capability

In order to help uCode debugging, adding the capability to provide
continuous uCode event logging function.

uCode events is located in round-robin event queue and filled by uCode,
by enable continuous event logging, driver check the write pointer
and log the newly added events in iwl_bg_ucode_trace() timer function.

There is still possibility of missing events if event queue being
wrapped before next event dump; but with this capability, we can have
much better understanding of the uCode behavior during runtime; it can
help to debug the uCode related issues.

Methods to enable/disable the continuous event log:
step 1: enable ucode trace timer
     "echo 1 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
step 2: start ftrace
     sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d
step 3: stop ftrace
     sudo ./trace-cmd report trace.dat
step 4: disable ucode trace timer
     "echo 0 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"

use "ucode_tracing" debugfs file to display number of event
queue wrapped when driver attempt the continuous event logging. If event
queue being wrapped more than once when driver has opportunity to log
the event; it indicated there are events missing in the event log trace.

This continuous event log function only available for 4965 and newer
NICs.

From b03d7d0fd3d23b7cf130fa702f4ae3b1bc827d4b Mon Sep 17 00:00:00 2001
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date: Mon, 14 Dec 2009 14:12:20 -0800
Subject: iwlwifi: on-screen event log dump

This feature enables the on-screen uCode event log dump. The original
method will append the event log to syslog; with this capability,
we also enable the user to write script to capture the
events which provide additional flexibility to help uCode debugging

Method
1) change to debugfs directory (sys/kernel/debug/phyX/iwlagn/data)
2) #cat log_event

Subject: iwlwifi: remove extra error msg on sensitivity calibration

Do not need to log error when fail the sensitivity command, driver will send
sensitivity write command to uCode after each sensitivity calibration if
station is associated with AP. It is a normal case when user unload the module
or shutdown the system while still associated with the AP, since uCode already
on the way down, it will not reply the sensitivity write request; report
error in this case will give misleading information, remove the error checking
here to provide a clean shutdown if no other error detected.

Subject: rt2x00 : trim the skb after having the l2pad removed.

Otherwise we end up truncating the skb before removing the l2pad
thus we might have the truncated part become garbage while getting
it back in remove_l2pad.
For the same issue: remove the skb_trim from the rt2800 fill_rxdone
(it is done after l2pad removal in rt2x00lib_rxdone).

Subject: rt2x00: Further L2 padding fixes.

Fix a couple of more bugs in the L2 padding code:
1. Compute the amount of L2 padding correctly (in 3 places).
2. Trim the skb correctly when the L2 padding has been applied.

Also introduce a central macro the compute the L2 padding size.

Subject: rt2x00: Remove SKBDESC_L2_PADDED flag.

With the improved L2 padding code, this flag is no longer necessary, as the
rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is
applied.
For received frames the RX descriptor flag is still being checked.

Subject: rt2x00: Reorganize L2 padding inserting function.

Simplify the rt2x00queue_insert_l2pad function by handling the alignment
operations one by one. Do not special case special circumstances.
Basically first perform header alignment, and then perform payload alignment
(if any payload does exist). This results in a properly aligned skb.

The end result is better readable code, with better results, as now L2 padding
is inserted only when a payload is actually present in the frame.

RX aggregation is a way to receive multiple 802.11 frames in one RX buffer.
However, we don't know yet how to handle this case in rt2800usb_fill_rxdone
and this has probably no impact on RX performance as well, so we disable it

Subject: rt2x00: Fix rt2800usb RX frame format and as such L2PAD

According to Ralink source code, the RX frame format is RXINFO + RXWI +
802.11 frame + RXD, including various padding. Before this patch, we
were using RXD + RXWI + 802.11 frame, so RXD was not correct.

Doing this, we fix the L2PAD bit which is now correctly set on received
frames.

Subject: mac80211: enable spatial multiplexing powersave

Enable spatial multiplexing in mac80211 by telling the
driver what to do and, where necessary, sending action
frames to the AP to update the requested SMPS mode.

Also includes a trivial implementation for hwsim that
just logs the requested mode.

For now, the userspace interface is in debugfs only,
and let you toggle the requested mode at any time.

Subject: libertas: use priv->mesh_tlv instead of priv->mesh_fw_ver

Both variables contained the same information (no mesh, old mesh, new mesh).
So we can get rid of one variable.

Also move the mesh-version test from cmd.c into mesh.c.

Subject: libertas: remove mesh_autostart_enabled and sync_channel

mesh_autostart_enabled was nowhere set. Rumor is that this is used in the
OLPC tree, but they never did submit their code upstream.

After removing this code, it turned out that the sync_channel stuff is now
also unused, so get rid of that as well.

Subject: libertas: make mesh configurable

Mostly for the embedded people that know beforehand that they don't need
MESH at all and want to save some bytes, but also helpful for the upcoming
cfg80211 transition.

Subject: libertas: remove priv->capability

This variable was once set to WLAN_CAPABILITY_SHORT_PREAMBLE and
there's no code that could change the variable to something else.
Therefore it seems this is not necessary :-)

Subject: mac80211_hwsim: Check all local addresses for TX Ack status

Since mac80211_hwsim supports multiple virtual interfaces, we need to
iterate through all active interfaces when figuring out whether there
is a match during TX Ack status checking. This fixes TX status
reporting for cases where secondary interfaces are used.

Subject: ath9k: add MCS rate index back to debufs rcstat

Speaking of 802.11n rates in terms of Mbps doesn't really developers
and is just useful for users. To aid debugging add the MCS index back
and an HT20/HT40 mode.

New screenshot:

The zd1211rw always assumed that the storage device is at endpoint 1,
but there are devices (Spairon Homelink 1202) that are at endpoint 0.
Try both, starting with 1 to make sure to not break existing setups.

Subject: mwl8k: do rx/tx ring initialisation after loading firmware

Whether the firmware we have loaded is AP or STA firmware decides
which receive descriptor format we have to use.  Therefore, move
rx/tx ring initialisation to be after firmware loading.

Subject: mwl8k: fix up AP vs. STA firmware image receive descriptor handling

The receive descriptor ops that are currently marked as being for
8687 only are actually used for all STA firmware images, whereas the
receive descriptor ops marked as 8366 are only used on 8366 when an
AP firmware image is in use.

Rename the receive descriptor ops to reflect this, use the STA ops
unconditionally if the firmware image loaded reported the STA ready
code, and rename the mwl8k_device_info::rxd_ops member to ap_rxd_ops
to indicate that it should only be used if we are running on AP
firmware.

Subject: b43: Allow PIO mode to be selected at module load

If userencounter the "Fatal DMA Problem" with a BCM43XX device, and
still wish to use b43 as the driver, their only option is to rebuild
the kernel with CONFIG_B43_FORCE_PIO. This patch removes this option and
allows PIO mode to be selected with a load-time parameter for the module.
Note that the configuration variable CONFIG_B43_PIO is also removed.

Once the DMA problem with the BCM4312 devices is solved, this patch will
likely be reverted.

Subject: wl1271: use join command with dummy BSSID

When we need to change the channel before association, we have to send a join
command with a valid BSSID.  With this patch we use 0baddeadbeef as the
BSSID.  There are ongoing discussions with TI to get this done in a cleaner
way.

When we go back to idle, we issue a CMD_DISCONNECT to make sure the firmware
stops listening to the channel and cleans things up internally.

Subject: wl1271: remove workaround for disconnection

Now we're using a the idle information coming from mac80211 to decide when to
disconnect.  If we have joined (ie. we're listening to a channel), whenever
the interface goes to idle, we will issue a disconnect command.  So the
workaround to send a disconnect command before joining is not needed anymore.

Subject: wl1271: limit TX power to 25dBm for every channel

The wl1271 firmware supports maximun 25.5dBm, so the driver was returning
-EINVALID to anything above that.  This patch uses the channel max_power
option to limit the TX power to 25dBm.

We were using CONF_TX_RATE_MASK_ALL when calling wl1271_acx_rate_policies()
during init.  We should use WL1271_DEFAULT_BASIC_RATE_SET instead.  The
values are the same, but the latter is just the correct macro to use.

Subject: wl1271: add gpio_power file in debugfs to power the chip on and off

Some debugging tools require the chip to be powered on before they can work.
With these tools, we shouldn't upload the firmware nor boot the firmware
ourselves, so this debufs file is provided.  It always contains the gpio
power setting (0 = off, 1 = on).  To change the power setting, just write 0
or 1 to the file.

Subject: wl1271: upload only the first 468 bytes from the NVS file

We were uploading the whole NVS file, but that is wrong, because the same
file also contains the initialization values.  For the latest firmwares, we
should upload only the initial 468 bytes from the file.

Subject: wl1271: use channel 1 when configuring the data path

In the data path configuration, one of the parameters is the channel.  We
have been setting it to wl->channel, which is not correct in this case.  This
channel has nothing to do with the channel we're currently tuned to, since it
is only used for calibration during this phase.  Hardcoded the channel to 1,
according to the reference driver.

Subject: wl1271: Use slow rates for association messages

While not associated, default the data rates to 1 and 2mbps, so that only
those rates will be used for association related message transfer. Once
associated, configure the full rate-set supported by the AP.

The wl1271 has a hardware bug which causes it to randomly (very infrequently)
to fail powering up properly. This patch implements retry for the chipset boot

Subject: wl1271: Add pre-power-on sleep

This patch adds a short delay before powering on the wl1271. Normally, it is
not needed, but if the wl1271 has been powered off shortly before, for reliable
firmware-booting this small stabilization delay is required.

Subject: wl1271: Add rudimentary ad-hoc support

This patch adds rudimentary a-hoc support for the driver. It will allow
setting up ad-hoc, and for other devices to scan and join. The beacon and probe
response template setting is slightly dirty, and need to be properly
implemented with support from mac80211. Also, the SSID is not configured to the
firmware - the FW will not be able to respond to probe requests autonomously.

Previously a "firmware chooses" value was used for the rates of all control
message templates set to the firmware. This resulted in a too high rate to be
chosen to transmit those messages. Change this by configuring a fixed low rate
for the templates.

Subject: wl1271: Add support for acx_pm_config

This acx configures host clock parameters in correspondence with the clock
request line - the settling time of the clock, and whether fast wake-up is
supported.

Subject: wl1271: Check vif for NULL when indicating beacon-loss

Because the interface is started and the vif are created and destroyed
separately, there is a slim possibility beacon-loss indications occur while
there is no vif - causing a kernel-oops unless checked.

Add checking for the vif.

Subject: rt2x00: Let rt2800lib check CONFIG_RT2X00_LIB_USB instead of
 CONFIG_RT2800USB

rt2800lib currently checks whether RT2800USB is enabled in the configuration.
Strictly speaking this is not necessary, it only needs to know whether the
generic rt2x00usb library functions are available. Therefore check for
RT2X00_LIB_USB instead.

Subject: rt2x00: convert RT2800PCI_PCI and RT2800PCI_SOC Kconfig symbols to
 booleans.

There is no need for Kconfig symbols RT2800PCI_PCI and RT2800PCI_SOC to be
tristates, as they are only used to check whether RT2800 PCI or SOC support
is to be compiled in.

Subject: rt2x00: Cleanup chip handling helper functions.

Let each of them take a struct rt2x00_dev pointer as argument instead of
a mixture of struct rt2x00_chip and struct rt2x00_dev pointers.
Preparation for further clean ups in the rt2x00 chip handling, especially
for rt2800 devices.

Subject: rtl8180: remove priv->mode

It is only checked in add_interface, and there it is easily replaced
with a check of priv->vif.  If that information should become necessary,
it is available in vif->type anyway.

Subject: rtl8187: remove priv->mode

It is checked in add_interface, but there it is easily replaced with
a check of priv->vif.  If that information should become necessary,
it is available in vif->type anyway.

It is also checked in led_turn_on and led_turn_off, where I made the
substitutions as described above.  Of course, these checks seem to
have been incorrect since the driver was using NL80211_IFTYPE_MONITOR
to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED.
Anyway, I think these checks may be extraneous...?

Subject: mac80211: introduce flush operation

We've long lacked a good confirmation that frames
have really gone out, e.g. before going off-channel
for a scan. Add a flush() operation that drivers
can implement to provide that confirmation, and use
it in a few places:
 * before scanning sends the nullfunc frames
 * after scanning sends the nullfunc frames, if any
 * when going idle, to send any pending frames

Subject: mac80211: remove struct ieee80211_if_init_conf

All its members (vif, mac_addr, type) are now available
in the vif struct directly, so we can pass that instead
of the conf struct. I generated this patch (except the
mac80211 and header file changes) with this semantic
patch:

@@
identifier conf, fn, hw;
type tp;
@@
tp fn(struct ieee80211_hw *hw,
-struct ieee80211_if_init_conf *conf)
+struct ieee80211_vif *vif)
{

-conf->type
+vif->type
|
-conf->mac_addr
+vif->addr

-conf->vif
+vif

Subject: wl1271: fix timeout in wl1271_top_reg_read

I noticed a timeout bug in

/drivers/net/wireless/wl12xx/wl1271_spi.c

In the current code you cannot tell why you exited
the "poll for data ready" do-while loop if exiting
was done after the last possible loop.

Then timeout==0 regardless of (val & OCP_READY_MASK) or
!(val & OCP_READY_MASK), leading to possible false timeout...

Simple correction could be decreasing timeout after checking
for !(val & OCP_READY_MASK), not before

(Manually converted from email to an actual patch by me. -- JWL)

Subject: iwlwifi: remove linux/utsrelease.h dependency

Commit 250cce26d5d03337aec4ff8405121f026adb4a89 uses UTS_RELEASE
as the the in-tree iwlwifi driver version. However the inclusion
of generated/utsrelease.h makes it a unpleasant behaviour to
recompile the driver everytime when utsrelease.h is updated. In
fact, the driver module is already built with the UTS_RELEASE
information via vermagic of modinfo. Mark the in-tree driver
with the version string "in-tree" to distinguish with those old
out-of-tree drivers.

Subject: mwl8k: handle station database update for AP's sta entry via
 ->sta_notify()

Inserting and removing a hardware station database entry for the AP
when we are in managed mode is currently done in ->bss_info_changed().

To prepare for adding AP mode support, implement the ->sta_notify()
driver method, and let that handle inserting and removing the hardware
station database entry for our AP instead.

From a680400e8ac32adda81b5e2d7f23dfac63e064fe Mon Sep 17 00:00:00 2001

Subject: mwl8k: move ->peer_id from mwl8k_vif to mwl8k_sta

For STA firmware, move the per-peer hardware station ID to the
driver-private part of struct ieee80211_sta, where it belongs.

(Since issuing a hardware station database maintenance command sleeps,
we can't hold a reference to the ieee80211_sta * across the command,
and since we won't know the station ID until after the command
completes, we need to re-lookup the sta when the command is done to
write the returned station ID back to its driver-private part.)

Subject: mwl8k: honor peer rate set

When calling SET_RATE, SET_AID, or when creating a station database
entry for our AP, pass in the AP's rate set instead of just blindly
enabling all legacy rates, so as to end up doing the right thing when
talking to 11b-only APs.

Subject: mwl8k: fix changed flags handling in mwl8k_bss_info_changed()

Previously, mwl8k_bss_info_changed() would refuse to do anything if
the 'changed' argument indicated that the association status hadn't
changed.  Fix this up so that it will allow changing things like the
preamble type, the slot time and the CTS-to-self protection method
without having to reassociate.

Subject: ath9k: re-enable ps by default for new single chip families

The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.

For more details on this issue see the bug report:

http://bugzilla.kernel.org/show_bug.cgi?id=14267

We leave AR5416 with PS disabled by default, that seems to require
some more work.

Subject: ath5k: Fix functions for getting/setting slot time

Functions ath5k_hw_get_slot_time and ath5k_hw_set_slot_time were
converting microseconds to clocks only for AR5210, although it's needed
for all supported devices. The conversion was moved outside the
hardware-specific branches.

The original code also limited minimum slot time to 9, while turbo modes
use 6, this was fixed too.

Subject: ath5k: Reimplement clock rate to usec conversion

The original code was correct in 802.11a mode only, 802.11b/g uses
different clock rates. The new code uses values taken from FreeBSD HAL
and should be correct for all modes including turbo modes.

The former rate calculation was used by slope coefficient calculation
function ath5k_hw_write_ofdm_timings. However, this function requires
the 802.11a values even in 802.11g mode. Thus the use of
ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope
coefficient calculation is not related to clock rate at all.

Subject: ath5k: Implement mac80211 callback set_coverage_class

The callback sets slot time as specified in IEEE 802.11-2007 section
17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS
timeouts accordingly. The values are persistent, they are restored after
device reset.

Subject: rt2x00: RF3052 is a valid RF chipset for USB devices as well.

The RF3052 chipset is now also being integrated onto USB devices, so
allow the RF chipset and don't treat it as PCI/SOC only.

Subject: wl1251: cleanup scanning code

The current scanning code wasn't following the preferred style. Move code
related to scan and trigger scan to commans to wl1251_cmd.c. Because
there's now less code in wl1251_hw_scan(), the function can be now
merged with wl1251_op_hw_scan().

Subject: wl1251: fix sleep related error paths in wl1251_op_bss_info_changed()

In various cases wl1251_op_bss_info_changed() did not call elp_sleep()
after an error was noticed. Fix it by using correct goto label.

The bug was a theoretical one, in practise it doesn't matter because
if commands start returning errors there will be lots of other problems.

Subject: mwl8k: undo transmit queue 0/1 swapping in
 mwl8k_cmd_set_edca_params()

The comment and code in mwl8k_cmd_set_edca_params() suggest that the
mapping between SET_EDCA_PARAMS queue numbers and transmit rings isn't
actually 1:1, while tests show that the mapping is in fact 1:1.  So,
get rid of the transmit queue 0/1 swapping.

Subject: mwl8k: bump the transmit wait timeout to 5 seconds

While it is reasonable to expect that at least one transmit ring entry
will be processed per second while we are waiting for the transmit
rings to drain, the firmware can end up doing batching of transmit ring
status writeback, which means that the transmit rings can appear stuck
for more than a second at a time.

Bump the TX drain wait timeout up from 1 to 5 seconds to account for
this.

As we always use the auto rate adaptation feature and never pass in
a rate table, USE_FIXED_RATE can be simplified somewhat.  While we're
at it, rename it to *_sta, as this is the STA version of the command.

As with the STA version, unicast will use auto rate adaptation, but
the AP version allows setting the rates to be used for management and
multicast transmissions, which can be set based on the BSS basic rate
set.

Subject: mwl8k: implement AP firmware station database maintenance

STA firmware uses UPDATE_STADB to manipulate the hardware station
database, whereas AP firmware uses SET_NEW_STN -- this implements the
latter, and hooks it into mwl8k_sta_notify(), to be used if we're
running on AP firmware.

Subject: mwl8k: allow limiting the amount of transmit reclaim done

Add a limit argument to mwl8k_txq_reclaim(), to allow limiting the
number of packets that it will reclaim, and make it return the number
of packets that it reclaimed.

Subject: mwl8k: keep TX_DONE interrupt masked while transmit reclaim is
 running

By making use of the CLEAR_SEL feature of the mwl8k host interface
interrupt controller, we can keep the TX_DONE interrupt source masked
while the transmit reclaim tasklet is running (NAPI style) without
having to touch the interrupt controller's interrupt mask register
when entering or exiting polling mode, and without having to do any
more register reads/writes than we do now.

When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading
the interrupt status register will clear the TX_DONE status bit if
it was set, allowing it to be set again if a new TX_DONE event arrives
while we are running the TX reclaim tasklet, but such a new event will
then not trigger another PCI interrupt until a zero is written to the
TX_DONE interrupt status register bit.

I.e., if we write a zero to the TX_DONE interrupt source bit in the
interrupt status register when the TX reclaim tasklet thinks it's
done, a PCI interrupt will be triggered if a new TX_DONE event arrived
from the hardware between us deciding that there is no more work to do
and re-enabling the TX_DONE interrupt source, thereby avoiding the
classic NAPI poll mode exit race that would otherwise occur.

Subject: mwl8k: move receive processing to tasklet

Like how TX reclaim is done in a tasklet, move receive processing
to tasklet context as well.  This can have nice benefits for CPU
utilisation and throughput, especially at 3-stream rates.

(Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to
avoid having to touch the interrupt mask registers.)

mac80211 do not check the return code now, what if mac80211 does start
using the return code? IEEE80211_AMPDU_TX_OPERATIONAL is a valid action,
just iwlwifi driver do not need to take any action for it; so instead of
return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP"
to make sure mac80211 will not get wrong impression.

Subject: mwl8k: properly set receive status rate index on 5 GHz receive

The mwl8k firmware uses indices into the 2.4 GHz band rate table for
the receive descriptor channel field even if the packet was received
on a 5 GHz channel, while mac80211 expects an index into the 5 GHz
band rate table when packets are received on the 5 GHz band, which
presents a mismatch as the 5 GHz band rate table lacks the five
non-OFDM rates that the 2.4 GHz rate table starts with.

To handle this properly, we need to substract 5 from the rate index
field if the packet was received on a 5 GHz channel (and was not
received at an MCS rate).

Subject: mwl8k: handle 5 GHz legacy rate bitmaps in firmware commands

Whenever mac80211 gives us a legacy rate bitmap in the context of the
5 GHz band, we need to remember to shift the bitmap left by 5 positions
before giving it to the firmware, as the firmware follows the bitmap
bit assignment of the 2.4 GHz rate table even if we're on the 5 GHz
band, and the 2.4 GHz rate table includes five non-OFDM rates at the
start that are not valid in the 5 GHz band.

Make the decision about whether to register the 2.4 and 5 GHz bands
with mac80211 by looking at the capability field in GET_HW_SPEC (STA
firmware only for now).  This enables 5 GHz STA operation.

Subject: mwl8k: prepare for posting per-vif firmware commands

One of the bytes in the mwl8k firmware command header is the 'macid'
byte, which for per-vif commands indicates which of the BSSes this
command is intended for.  (For commands that are not per-vif commands,
this byte can just be 0.)

This patch adds mwl8k_post_pervif_cmd(), which will take the macid
assigned to this interface (to be done in ->add_interface()), copy it
into the command packet macid field, and post the command as usual.

Subject: mwl8k: post per-vif firmware commands as per-vif commands

SET_BEACON, SET_MAC_ADDR, BSS_START and SET_NEW_STN are the currently
supported firmware commands that are actually per-vif commands.  Use
mwl8k_post_pervif_cmd() for these commands, so that the macid of the
vif they operate on gets passed down into the firmware.

Subject: mwl8k: enable multi-BSS AP operation

As follows:
- GET_HW_SPEC is now responsible for setting
  priv->{ap,sta}_macids_supported, which are bitmasks of supported
  macids for AP and STA mode.  (Typically, STA firmware images will
  support only one macid, #0, in STA mode, and AP firmware images
  will support macids #0-7, in AP mode.)
- Our wiphy ->interfaces_modes is now set based on the non-zero-ness
  of these two bitmasks.
- We main priv->macids_used, a bitmask of which macids are currently
  in use.  ->add_interface() will assign the lowest free macid for
  this interface type as it is created, or bail out if there are no
  more free macids to assign.  ->delete_interface() will mark the
  macid as being free again.

This enables the multi-BSS code added in the previous commits.

These are unused and as with a previous patch 5ef5da for wl1251
this removes some other unused flags. the IRQ_MASK specifically

Subject: Remove config option B43_LEGACY_RFKILL completely

In f41f3f373dd72344c65d801d6381fe83ef3a2c54 the B43 driver was ported
to use the cfg80211 API for rfkill and consequently the config option
was dropped (RFKILL is now unconditionally enabled).

However in the Kernel Info the feature is still checked and reported
missing. This patch just removes the conditional and the relevant code
blocks while still reporting that feature unconditionally would be
another option (it's always there).

Subject: ath9k: Fix panic on driver load

The device has to be marked as invalid before
registering the ISR. HW initialization takes place
after the ISR has been registered, and the invalid
flag is eventually cleared in the ->stop() callback.

Subject: ath9k: cleanup slot time and ack/cts timeout handling

Previously ath9k left the initialization of slot timing and ACK/CTS
timeout to the mode specific initvals. This does not handle short vs
long slot in 2.4 GHz and uses a rather strange value for the 2.4 GHz
ACK timeout (64 usec).
This patch uses the proper ath9k_hw functions for setting slot time and
timeouts and also implements the switch between short and long slot
time in 2.4 GHz

Subject: b43: N-PHY: clean table init, check PHY rev
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move table init to tables_nphy.c, detect newer PHY which use different init.
We don't init newer PHYs yet but this at least shows what more is needed.

Subject: b43: N-PHY: update init code to match current specs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous init path was based on old specs from old driver. Update it
as much as possible leaving some TODOs for not implemented functions.

Subject: iwlwifi: add num_of_sos_stats to statistics counter

When uCode detects number of beacon missed consecutively above the
internal missed beacon threshold (set by uCode), it will reset and
re-tune the radio in order to get out of bad PHY state.

This "num_of_sos_states" counter monitors number of time uCode
encounters this bad condition and has to re-tune the radio.

Subject: iwlwifi: software w/a for h/w bug cause Rx bit get clear

This is a w/a for a hardware bug. the h/w bug may cause the Rx bit
(bit 15 before shifting it to 31) to clear when using interrupt coalescing.

This does not mean frames are lost - their processing is just delayed until
next interrupt arrives.

Subject: iwlwifi: display flowhandler register when sw error or on-demand

Flowhandler handle the communication between driver and uCode, when any
uCode error happen, we also like to know what is the status of the
flowhandler; it can help to debug flowhandler related problem.

Also adding debugfs file to dump current value of flowhandler registers.

Subject: iwlwifi: remove extra statistics request from debugfs

When reading current ucode statistics information from debugfs, in
current implementation, it will always send a new "statistics request" to
uCode. In normal operation, uCode should report the statistics per beacon
interval. Remove this extra request to reduce the additional command exchanges
between driver and uCode.

Subject: ath9k: fix RTS/CTS handling

The Tx DMA descriptor has two kinds of flags that select RTS/CTS usage.
The first one (global for the frame) selects whether RTS/CTS or
CTS-to-self should be used, the second one enables RTS/CTS or
CTS-to-self usage for an individual multi-rate-retry entry.
Previously the code preparing the descriptor only enabled the global
flag, if the first MRR series selected the local one.
Fix this by enabling the global flag if any of the MRR entries need it.
With this patch, rate control can properly select the use of RTS/CTS
for all MRR entries except the first one, which is the default behavior.

Subject: p54pci: move tx cleanup into tasklet

This patch moves the tx cleanup routines out of the critical
interrupt context and into the (previously known as rx) tasklet.

The main goal of this operation is to remove the extensive
usage of spin_lock_irqsaves in the generic p54common library.

The next step would be to modify p54usb to do the
rx processing inside a tasklet (just like usbnet).

Subject: libertas: Set/clear WPA keys before the WEP ones

With the v10 firmware running on 8688 HW, clearing WPA keys after setting the
WEP key prevents us from being able to associate with WEP APs.
Swapping the calling order for assoc_helper_wpa_keys() and
assoc_helper_wep_keys fixes that issue.

Subject: ath9k: make tx power config changes take effect immediatley

Users wishing to tweak tx power want it to happen immediately,
try to respect that. This was tested by Lorenzo by measuring the
received signal strength from an AP with ath9k and the patch.

Changing the tx power on the AP produced these results:

1) iwconfig wlan0 txpower 20 ---> Rx power -37dbm
2) iwconfig wlan0 txpower 15 ---> Rx power -41dbm
3) iwconfig wlan0 txpower 10 ---> Rx power -45dbm
4) iwconfig wlan0 txpower 5 ---> Rx power -51dbm
5) iwconfig wlan0 txpower 0 ---> Rx power -37dbm

The result with 0 is an anomoly and would need to be
addressed through a separate patch.

Subject: mac80211: pass vif and station to update_tkip_key

When a TKIP key is updated, we should pass the station
pointer instead of just the address, since drivers can
use that to store their own data. We also need to pass
the virtual interface pointer.

Subject: cfg80211: export multiple MAC addresses in sysfs

If a device has multiple MAC addresses, userspace will
need to know about that. Similarly, if it allows the
MAC addresses to vary by a bitmask.

If a driver exports multiple addresses, it is assumed
that it will be able to deal with that many different
addresses, which need not necessarily match the ones
programmed into the device; if a mask is set then the
device should deal addresses within that mask based
on an arbitrary "base address".

To test it all and show how it is used, add support
to hwsim even though it can't actually deal with
addresses different from the default.

Subject: ath5k: dont use external sleep clock in AP mode

When using the external sleep clock in AP mode, the
TSF increments too quickly, causing beacon interval
to be much lower than it is supposed to be, resulting
in lots of beacon-not-ready interrupts.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14802.

Subject: ath5k: fix setup for CAB queue

The beacon sent gating doesn't seem to work with any combination
of flags.  Thus, buffered frames tend to stay buffered forever,
using up tx descriptors.

Instead, use the DBA gating and hold transmission of the buffered
frames until 80% of the beacon interval has elapsed using the ready
time.  This fixes the following error in AP mode:

   ath5k phy0: no further txbuf available, dropping packet

Add a comment to acknowledge that this isn't the best solution.

As all bt packets are priority traffic during bt scan, wifi
will get disconnected when bt scan lasts for few seconds. Fix
this by allocating 10% of bt period time (4.5ms) to wifi fully.

Subject: iwlwifi: configure missed beacon threshold

Add support to configure missed beacon threshold, by default, if receive
"missed beacon" notification from uCode and has more than 5 consecutive
beacon missed, then perform sensitivity calibration; with this change,
allow user to adjust the missed beacon threshold from debugfs in case
more sensitivity calibration required for better performance in noisy
environment

The default value (=5) should be good enough for the normal condition,
but for very noisy environment, more sensitivity calibration could help
improve the throughput, so by setting the missed beacon threshold to
lower number, user might experience better performance result.

Subject: iwlwifi: add function to reset/tune radio if needed

Adding "radio reset" function to help reset and stabilize the radio.

During normal operation, sometime for unknown reason, radio encounter
problem and can not recover by itself; the best way to
recover from it is to reset and re-tune the radio. Currently, there is
no RF reset command available, but since radio will get reset when
switching channel, use internal hw scan request to force radio
reset and get back to normal operation state.

The internal hw scan will only perform passive scan on the first
available channel (not the channel being used) in associated state. The
request should be ignored if already performing scan operation or STA is
not in associated state.

Also include an "internal_scan" debugfs file to help trigger the
internal scan from user mode.

Subject: iwlwifi: Fix A band scanning when associated

This patch allows A band to be scanned when driver is associated to AP.
Scan mechanism is that mac80211/cfg80211 requests driver to scan G band
first and then immediately to scan A band. Original code require
driver to wait for 2 seconds after any scan before another scan will be
performed. This caused driver to service G band scan request from
mac80211/cfg80211 but deny the A band scan request.

Subject: iwlwifi: Logic to control how frequent radio should be reset if
 needed

Add additional logic for internal scan routine to control how
frequent this function should be performed.

The intent of this function is to reset/re-tune the radio and bring the
RF/PHY back to normal state, it does not make sense calling it too
frequent,
if reset the radio can not bring it back to normal state, it indicate
there are other reason to cause the radio not operate correctly.

Subject: iwlwifi: Tune radio to prevent unexpected behavior

We have seen the throughput dropped due to external noisy environment
and the radio is out of tune.  There are lot of plcp errors indicating
this condition. Eventually the station can get de-authenticated by the
Access Point.  By resetting and tuning the radio, the plcp errors are
reduced or eliminated and the throughput starts to rise.

To prevent unexpected behavior such as drop in throughput or deauthentication,
- The change provides the driver feature to monitor and tune the radio base on
the statistics notification from the uCode.
- It also allows the setting of the plcp error rate threshold via
the plcp_delta under debugfs interface.

Subject: iwlwifi: cleanup station adding code

The work done when a station is added is very similar whether the station
is added synchronously or asynchronously. Centralize this work. At the same
time increase the status flags being checked for when the command returns
with accompanying debug messages. Also increase checking when setting the
"ucode active" state with accompanying debugging.

This work is done in preparation for station notification support.

Subject: iwlwifi: make broadcast station addition generic

Add function pointer for broadcast station addition so that we can call it
in from iwlcore at a later time. We only distinguish between iwlagn and
iwl3945 broadcast station addition. For the iwl3945 station addition we add
that function to iwlcore since that is where most station functionality
resides, making it part of iwl3945 will require significant code
reorganization that will dilute station management functionality. This
seems to be an efficient solution.

It may seem as though we are removing error checking when adding the 3945
broadcast station but this error checking was never really necessary since
the function returns the station id and the broadcast station id is always
set.

Subject: iwlwifi: module parameter to enable/disable bt co-exist

Adding "bt_coex_active" module parameter for iwlcore to enable/disable
BT coexist; if bt_coex_active is true (default), uCode will do kill/defer
every time the priority line is asserted (BT is sending signals on the
priority line in the PCIx). By disable the bt_coex_active, uCode will
ignore the BT activity and perform the normal operation.

Users might experience transmit issue on some platform due to this
WiFi/BT co-exist problem. The possible symptoms are: NetworkManager and
other similar programs can scan and find all the available APs, but will
timeout and unable to associate with any of the APs; no out-going frames
can be found with wireless sniffer tools.

On those platforms, WiFi communication can be restored by set "bt_coex_active"
module parameter to "false"

Subject: iwlwifi: reorder device setup

It is better to first notify cfg80211 about the hw
rfkill state (so the rfkill device that will be
registered won't have the wrong state while being
registered), and the power/tt variable init can
(and probably should) also be done first.

Also rename iwl_setup_mac to
iwl_mac_setup_register to better describe what it
really does.

Subject: iwlwifi: clean up debugfs code

The debugfs code can be made a whole lot more
efficient by using debugfs_remove_recursive(),
the large chunk of variables can completely go
away and by moving two variables we no longer
need to allocate an extra chunk of memory.

Subject: iwlwifi: cleanup spectrum measurement command support

In iwlagn the support for spectrum measurement command has been
disabled since v2.6.29 without any requests for it. In addition to this
when this command is indeed enabled it has been found to trigger firmware
SYSASSERT on at least 4965 and 5100 hardware (see
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
this code has been bitrotting and cannot just be enabled without porting.

Remove support for spectrum measurement command from iwlagn. It can be
added back if there is a future need and the firmware problem it triggers
has been fixed. Support for the spectrim measurement notification remains
as it has been enabled all the time.

In addition to this remove the 3945 spectrum measurement command Kconfig
option and make this command always supported. The code added by this
enabling is minimal and only run when user triggers a spectrum measurement
request via sysfs.

Subject: iwlwifi: fix throughput degradation in aggregation mode

The following commit

	commit e4da8c37af626001ff704fb29ea14eb58f5f7208
	Author: Johannes Berg <johannes@sipsolutions.net>
	Date:   Wed Dec 23 13:15:43 2009 +0100

	   mac80211: make off-channel work generic

triggered a bug in iwlwifi where HT parameters would not be correctly set in
some mac80211 pathways. The aggregation (and possibly other) station flags were
not being set, which limited the size of aggregation blocks and reduced
throughput at high rates.

>From Johannes:
"""
Due to Wey-Yi's patch to use the set-channel command when the channel changes
while associated, we don't get a full new RXON. Therefore, we don't re-set the
rxon-station either. However, under some circumstances that apparently have
gotten more likely mac80211 will first set up the BSS info, then add the
station and then switch to an HT channel type.

Therefore, the check for "priv->current_ht_config.is_ht" in
iwl_rxon_add_station() will hit false and not fill in the HT information.

However, that check can just be removed, which is the easiest fix for all this,
because the HT capa struct is always there, just could possibly have the
ht_supported member set to false.
"""

A sample good link in my 3x3 network improves by approximately 25% TCP
throughput. This fixes Bug 2144
(http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2144).

Subject: ath9k: improve max rate retry handling

ath9k currently forces hw->max_rate_tries to 4 to work around rate
control inefficiencies. This has some negative side effects, such as
rate_control_send_low also using a maximum of 4 tries, which could
negatively affect reliability of unicast management frames.
This patch pushes the retry limit to the rate control instead, and
allows it to use more tries on the last stage to prevent unnecessary
packet loss.

Subject: b43: Workaround circular locking in hw-tkip key update callback

The TKIP key update callback is called from the RX path, where the driver
mutex is already locked. This results in a circular locking bug.
Avoid this by removing the lock.

Johannes noted that there is a separate bug: The callback still breaks on SDIO
hardware, because SDIO hardware access needs to sleep, but we are not allowed
to sleep in the callback due to mac80211's RCU locking.

Subject: mac80211: wait for beacon before enabling powersave

Because DTIM information is required for powersave
but is only conveyed in beacons, wait for a beacon
before enabling powersave, and change the way the
information is conveyed to the driver accordingly.

mwl8k doesn't currently seem to implement PS but
requires the DTIM period in a different way; after
talking to Lennert we agreed to just have mwl8k do
the parsing itself in the finalize_join work.

Subject: iwlwifi: optimize power saving

In hostap AP mode, every time the client sends the AP
a packet the STA_NOTIFY_AWAKE code is sent from mac80211.
This results in a command being sent to the uCode even if
the client was not asleep.

The following simple patch has fixed the issue for me without any
degradation that I can find.

The corresponding iwl_mac_remove_interface only

doesn't actually acquire the mutex around the
vif pointer check and assignment, fix that.

Due to a typo, the variable contains OFDM

so this change doesn't really do anything
but fix up my confusion.

Subject: iwlwifi: iwl_power_update_mode always hold mutex

iwl_power_update_mode expects to be called with mutex held, for example to
protect priv->vif. Only one caller currently does not do this, fix this.
Also, add a comment to iwl_power_update_mode to indicate this requirement.

Subject: ath9k: fix access to freed data on unload

Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access
to common->bus_ops, which is already freed as part of the device data.

Remove the cleanup field in struct ath_bus_ops, as it was never used
properly.  Remove ath_bus_cleanup().  Merge cleanup functions in place
of the ath_bus_cleanup() calls.  Take care not to use any device data
after ieee80211_free_hw().

Subject: airo: fix setting zero length WEP key

Patch prevents call set_wep_key() with zero key length. That fix long
standing regression since commit c0380693520b1a1e4f756799a0edc379378b462a
"airo: clean up WEP key operations". Additionally print call trace when
someone will try to use improper parameters, and remove key.len = 0
assignment, because it is in not possible code path.

802.11n but ath9k can still support them. These are called
AR2427.

Subject: mac80211_hwsim: add fake hw scan handler

For debugging hardware scan trigger/complete
functionality, it was useful to have code in
hwsim that pretends to do a hardware scan.

This code could be extended to actually do the
scan, but for now it was sufficient for me to
only pretend. Since hwsim was written to ease
debugging, it only makes sense to add it to it
permanently.

Subject: b43/b43legacy: Wake queues in wireless_core_start

If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.

In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

Subject: wl1251: fix txop unit

mac80211 uses unit units of 32 usec with txop but wl1251_acx_ac_cfg()
expects it to be usecs. This fortunately didn't cause any severe problems,
only that firmware was using incorrect WMM settings.

Subject: libertas: don't retry commands

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.

Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

Subject: iwlwifi: Add chain noise scaling factor

6x50 device requires a different scaling factor for Rx gain values sent to
device via PHY_CALIBRATION_CMD (CHAIN_NOISE_GAIN_CMD).  Rather than create
a new iwlXXXX_gain_computation() function, add new chain_noise_scale member
to struct iwl_cfg, and keep using iwl5000_gain_computation().

Subject: iwlwifi: Add chain_noise support for 6050

Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset).  As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate

Subject: iwlwifi: Send broadcast probe request only when asked to

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

get_tx_stats() will be removed from mac80211.

mwl8k used struct ieee80211_tx_queue_stats internally to track the queue
lenght. Replace struct ieee80211_tx_queue_stats with a simple len field
in struct mwl8k_tx_queue. Limit and count fields seemed to be unused.

Subject: p54: remove get_tx_stats() mac80211 op

get_tx_stats() will be removed from mac80211.

p54 uses struct ieee80211_tx_queue_stats also internally, so create a new
identical struct p54_tx_queue_stats which the driver can use.

Compile-tested only.

Subject: ath5k: use correct packet type when transmitting

The hardware needs to know what type of frames are being
sent in order to fill in various fields, for example the
timestamp in probe responses (before this patch, it was
always 0).  Set it correctly when initializing the TX
descriptor.

Subject: iwlwifi: multiple force reset mode

Provide the function to perform different type of uCode reset/reload operation.
When uCode detect error and can not fix itself, this iwl_force_reset()
function allow driver to perform the necessary reset/reload functions and help
to bring uCode back to normal operation state.

Currently only 2 type of force reset are available:
 - reset radio
 - reload firmware

Subject: iwlwifi: check for aggregation frame and queue

Error checking for aggregation frames should go into aggregation queue,
if aggregation queue not available, use legacy queue instead.
Also make sure the aggregation queue is available to activate,
if driver and mac80211 is out-of-sync, try to disable the queue and
sync-up with mac80211.

Subject: iwlwifi: fix scan race

There is a problem if an "internal short scan" is in progress when a
mac80211 requested scan arrives. If this new scan request arrives within
the "next_scan_jiffies" period then driver will immediately return success
and complete the scan. The problem here is that the scan has not been
fully initialized at this time (is_internal_short_scan is still set to true
because of the currently running scan), which results in the scan
completion never to be sent to mac80211. At this time also, evan though the
internal short scan is still running the state (is_internal_short_scan)
will be set to false, so when the internal scan does complete then mac80211
will receive a scan completion.

Fix this by checking right away if a scan is in progress when a scan
request arrives from mac80211.

Subject: iwlwifi: reset card during probe

To ensure that card is in a sane state during probe we add a reset call.
This change was prompted by users of kdump who was not able to bring up the
wireless driver in the kdump kernel. The problem here was that the primary
kernel, which is not running at the time, left the wireless card up and
running. When the kdump kernel starts it is thus possible to immediately
receive interrupts from firmware after registering interrupt, but without
being ready to deal with interrupts from firmware yet.

Subject: iwlwifi: Adjusting PLCP error threshold for 1000 NIC

While testing the station with the NIC 1000 family, it is found that
the plcp error can easily exceed 50 value in 100mSecs.  This creates
unneccessary radio reset/tuning.  This patch raises the PLCP error
threshold of the NIC 1000 from 50 to 200 error count.

Subject: iwlwifi: clear all the stop_queue flag after load firmware

All the queues are awake and ready to use after loading firmware,
for firmware reload case, if any queues was stopped before
reload, mac80211 will wake those queues after restart hardware, so make
sure all the flag used to keep track of the queue status are
reset correctly.

Subject: iwlwifi: Monitor and recover the aggregation TX flow failure

This change monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the expected_
ack_count also drops.  At the same time, the aggregated ba_timeout (the number
of ba timeout retries) also rises.  If the actual_ack_count/expected_ack_count
ratio is 0 and the number of ba timeout retries rises to 16, no tx packets
(tcp, udp, or ping - icmp) can be delivered.  The driver recovers from this
situation by reseting the uCode firmware.  If the actual_ack_count/expected_
ack_count ratio drops below 50% (but not 0) and the aggregated ba_timeout
retries just exceed 5 (but not 16), then the driver can reset the radio to
bring the throughput up.

Subject: ath9k: add a workaround for ack timeout issues

Adding support for setting the coverage class in some cases broke
association and data transfer, as it overwrote the initial ACK timeout
value from the initvals with a smaller value.
I don't know why the new value works in 5 GHz (matches the initval
there), but not in 2.4 GHz (initvals use 64us here), so until the
problem is fully understood, the value should be increased again.

Subject: net: use netdev_mc_count and netdev_mc_empty when appropriate

This patch replaces dev->mc_count in all drivers (hopefully I didn't miss
anything). Used spatch and did small tweaks and conding style changes when
it was suitable.

It needs to include net/iw_handler.h and it should select
WEXT_PRIV, like the airo driver does.

From 714fa6636331d33c6045efe394f36c964a6c14ee Mon Sep 17 00:00:00 2001
From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Sat, 13 Feb 2010 20:55:48 +0100
Subject: rt2x00: Reorganize RT chipset setting for PCI/SOC devices.

Don't set the RT chipset for a device from within the generic PCI/SOC code,
but rather from the individual drivers, so that individual drivers have
more control over what RT chipset is set.
Preparation for chip handling updates for rt2800 devices.

From 49e721ec6ca74f90ee99089ad2de1c338a95c6d5 Mon Sep 17 00:00:00 2001
From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Sat, 13 Feb 2010 20:55:49 +0100
Subject: rt2x00: rework RT chipset and revision determination for PCI an SOC
 devices.

The recent rt2800 devices are no longer really identified by their PCI
ID's, but rather by the contents of their CSR0 register. Also for the
other chipsets is the contents of this CSR0 register important.
Change the chipset determination logic to be more aligned with the rt2800
model.
Preparation for the support of rt3070 / rt3090 based devices.

From de1ebdceb6a4fe1b7073b81d273285b7c8bed312 Mon Sep 17 00:00:00 2001
From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Sun, 14 Feb 2010 12:52:05 +0100
Subject: rt2x00: rt2800 - Make rt30xx and rt35xx chipsets configurable.

Support for rt30xx- and rt35xx-based devices is currently not functional
in rt2800pci and rt2800usb.
In order to not confuse users we shouldn't claim the PCI and USB device
ID's for these devices. However, to allow for testing it is good to still
have them available, although disabled by default.
Make support for these device configuration options that default to off.

For rt2800usb a 3rd class of devices is added, which are the unknown
devices. For these devices it is known that they are either based on
rt28xx, rt30xx or rt35xx, but it is not known on what chipset exactly.
These devices are disabled by default as well, until it can be established
on what chipset exactly they are based.

Subject: mwl8k: disable softirqs when accessing sta_notify_list

Use spin_[un]lock_bh in mwl8k_sta_notify().  The sta_notify handler is
required to be atomic, yet it can be called in process context, so make
sure one call won't preempt another.

From 60b86755929e1a7e9038c8d860a8491cfdf8d93a Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Wed, 17 Feb 2010 10:30:23 +0000
Subject: usbnet: Convert dev(dbg|err|warn|info) macros to netdev_<level>

These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

Fix net1080 this/other log message inversion.

From fbc87d67af5ccd733f894273b215564c67e3a749 Mon Sep 17 00:00:00 2001
From: Pavel Roskin <proski@gnu.org>
Date: Thu, 11 Feb 2010 17:56:06 -0500
Subject: Introduce PCMCIA_DEVICE_PROD_ID3

...and use it in hostap_cs and orinoco_cs.

Another PCMCIA device with Intersil Prism chipset has been reported:

Socket 0:
  product info: "Gigabyte", "GN-WLM01_P25L_ADAPTER", "ISL37300P", "Eval-RevA"
  manfid: 0x02e0, 0x1011
  function: 6 (network)

As it's the case with some other Prism based devices, the third ID
string contains a design name that should be sufficient to identify the
card as having Intersil Prism chipset and thus compatible with both
orinoco_cs and hostap_cs.

Introduce PCMCIA_DEVICE_PROD_ID3 that matches the third ID string only.

Use it in orinoco_cs and hostap_cs to match cards with the third ID
string indicating Prism chipset.  Remove corresponding entries that use
PCMCIA_DEVICE_PROD_ID123.

Subject: wl1271: Fix PSM entry

Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and
beacon filtering to be illegally enabled (because FW remains in active state.)

Fix this by enabling ELP, BET and beacon filtering only after successful entry,
and by ensuring the firmware is in active mode after the failure.

Subject: wl1271: Fix channel changing code

The channel changing code would a) change the BSSID to a dummy on upon
channel change, breaking connectivity, and b) not update the channel number
at all for ad-hoc, breaking adhoc.

Subject: wl1271: Add SSID configuration for JOIN in ad-hoc

This patch adds code to extract the SSID from the beacon template used for
ad-hoc. The mac80211 currently does not provide the SSID, so this is a
workaround for that, for now.

Subject: wl1271: implement WMM

Now that necessary commands for WMM are implemented, implement queue handling
for WMM. But WMM is not enabled yet, only one queue is used.

Based on a similar patch from wl1251.

Subject: wl1271: Use NVS INI file configuration

Replace the hardcoded general and radio parameter configuration in the driver
with configuration taken from the NVS file directly. Also remove the driver
dependency to the structures with the parameter data.

Subject: wl1271: Retrieve device mac address from the nvs file

Instead of always randomizing the MAC address, retrieve and configure the
MAC address from the device specific nvs file. For now, randomize an address
only if the address in the NVS is zero.

Subject: wl1271: add most of the normal initialization commands to PLT mode

We need to configure PLT mode almost in the same way as normal mode.  Most of
the configuration functions need to be called also when entering PLT, with
the exception of a few RX and TX configuration (which cause mac80211 warnings
if enable while runnning PLT tests).

Subject: wl1271: skip 3 unused bytes from the NVS

Our NVS uploading mechanism had a bug that was causing it to pass three extra
zeros at the start of the NVS.  This may be a problem in the NVS generation
application, but for now we fix it in the driver.

Subject: wl1271: Fix random MAC address setting

If reverting to a random MAC address, the driver would not update it to the
NVS file, and hence the firmware frame filtering would not work properly.

So update the randomized MAC address to the NVS image.

Instead of acking RX packets read from the FW once all (of several possible)

enables the FW to start receiving more packets from the network while the
host read operation is still ongoing.

From 5c0ba62fd4b2dce08055a89600f1d834f9f0fe9e Mon Sep 17 00:00:00 2001
From: Felix Fietkau <nbd@openwrt.org>
Date: Fri, 19 Feb 2010 01:46:36 +0100
Subject: ath9k: fix rate control fallback rate selection

When selecting the tx fallback rate, rc.c used a separate variable
'nrix' for storing the next rate index, however it did not use that as
reference for further rate index lowering. Because of that, it ended up
reusing the same rate for multiple multi-rate retry stages, thus
decreasing delivery probability under changing link conditions.

This patch removes the separate (unnecessary) variable and fixes
fallback the way it was intended to work.
This should result in increased throughput and better link stability.

iwl3945 includes iwl-core.h in which these STATUS flags are already
defined. This also removes a potential confusing definition with iwlcore
using STATUS_MODE_PENDING with value 18 and iwl3945 defining (but not
using) STATUS_CONF_PENDING for value 18.

Subject: iwlwifi: enable serialization of synchronous commands

Until now it was only possible to have one synchronous command running at
any time. If a synchronous command is in progress when a second request
arrives then the second command will fail. Create a new mutex specific for
this purpose to only allow one synchronous command at a time, but enable
other commands to wait instead of fail if a synchronous command is in
progress.

Subject: iwlwifi: separated time check for different type of force reset

Use different timing duration check for different type of force reset,
force reset request can come from different source and based on
different reason; one type of reset request should not block other type of
reset request.

Adding structure to keep track of different force reset request.

Subject: ath9k: fix beacon timer restart after a card reset

In AP mode, ath_beacon_config_ap only restarts the timer if a TSF
restart is requested. Apparently this was added, because this function
unconditionally sets the flag for TSF reset.

The problem with this is, that ath9k_hw_reset() clobbers the timer
registers (specified in the initvals), thus effectively disabling the
SWBA interrupt whenever a card reset without TSF reset is issued
(happens in a few places in the code).

This patch fixes ath_beacon_config_ap to only issue the TSF reset flag
when necessary, but reinitialize the timer unconditionally. Tests show,
that this is enough to keep the SWBA interrupt going after a call to
ath_reset()

Subject: mwl8k: convert to new station add/remove callbacks

This converts mwl8k to use the new station
add/remove callbacks instead of using the
old sta_notify callback.

The new callbacks can sleep, so a lot of
code can be removed now.

Subject: Revert "iwlwifi: Monitor and recover the aggregation TX flow failure"

This reverts commit 1db5950f1d0b82e07371b211a48317b8972da063.

The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure"
is to first detect when data transmission stalls and then to recover from
this situation with a reset of the radio or the firmware, depending on how
bad the transmission failures are.

Unfortunately we have found that this change causes excessive resets with
its current detection algorithm. It also performs its recovery action when
none is really needed, like when we are not associated.

Revert this change until the issues have been addressed.

Subject: iwlwifi: increase command buffer size

Increase the buffer size for commands with "huge"
bit set. This has been recently observed for 6050 cards where
for even with huge bit set few commands were not properly allocated
memory with the command overwriting the buffer allocated for it..
Also add a check to see if command size exceeds the
maximum allowable size.

Subject: ath9k: disable RIFS search for AR91xx based chips

While ath9k does not support RIFS yet, the ability to receive RIFS
frames is currently enabled for most chipsets in the initvals.
This is causing baseband related issues on AR9160 and AR9130 based
chipsets, which can lock up under certain conditions.

This patch fixes these issues by overriding the initvals, effectively
disabling RIFS for all affected chipsets.

Subject: b43: fall back gracefully to PIO mode after fatal DMA errors

This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.

The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

(Some post-2.6.33 merge fixups by Larry Finger <Larry.Finger@lwfinger.net>
and yours truly... -- JWL)
