Subject: iwlwifi: use generic mac80211 radiotap headers

remove drivers own implementation of radiotap in favor of the generic one
provided by mac80211.

also remove priv->add_radiotap because it is not used any more.

Subject: iwlwifi: add level for debugging host command

This patch adds another level for debugging host command. This adds an
option to suppress the debug prints for sensitivity and link quality
commands.

Subject: cfg80211: keep track of supported interface modes

It is obviously good for userspace to know up front which
interface modes a given piece of hardware might support (even
if adding such an interface might fail later because of
concurrency issues), so let's make cfg80211 aware of that.
For good measure, disallow adding interfaces in all other
modes so drivers don't forget to announce support for one mode
when they add it.

This patch allows variable number of init calibrations and allows
addition new HW.

This patch also fixes critical bug. Only last calibration result
was applied. On reception of one calibration result all the calibration
was freed.

Subject: iwlwifi: allow association on radar channel in power save

This patch disables power save upon association and enables it back
after association. This allows to associate to AP on a radar channel
if power save is enabled.

Radar and passive channels are not allowed for TX (required for association)
unless RX is received but PS may close the radio and no RX will be received
effectively failing association.

Subject: iwlwifi: enable packet injection for iwlagn
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Handle station IDs of transmitted packets when in monitor mode, and
remove the various anti-injection checks from the iwl4965 driver.
This makes injection work on iwl4965 and iwl5000. Tested on both cards.

Note: To inject management frames with encryption, HW crypto support
must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1"
for iwl5000). Otherwise most management frames won't be transmitted.

Subject: iwlwifi: use the results from disconnected antenna algorithm

This patch makes usage of the results from disconnected antenna alg to
know how many antennas are connected.

It also synchronizes between the chain noise alg and the W/A that
disables power management during association. All the antennas must be
enables during the chain noise algorithm. Hence, power management is
restored only after the completion of the algorithm.

In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

Subject: iwlwifi: remove uneeded declarations

This patch cleans up iwlwifi by removing uneeded declarations and removing
uneeded symbol export reducing the namespace pollution. It also fixes some
typos in comments.

Subject: iwlwifi: fix searching for best rate in new search column

This patch fixes a bug in Rate Scaling. When moving from SISO to MIMO we
need to choose the lowest higher rate, instead of choosing the highest in MIMO.
No doing this can lead to a high packet loss in the highest rate in MIMO,
leading not to move MIMO although lower in MIMO could give a better TPT.

From 05c914fe330fa8e1cc67870dc0d3809dfd96c107 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Thu, 11 Sep 2008 00:01:58 +0200
Subject: mac80211: use nl80211 interface types

There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

Subject: mac80211: share STA information with driver

This patch changes mac80211 to share some more data about
stations with drivers. Should help iwlwifi and ath9k when
 they get around to updating, and might also help with
implementing rate control algorithms without internals.

Subject: mac80211: move txrate_idx into RC algorithms

The sta_info->txrate_idx member isn't used by all RC algorithms
in the way it was intended to be used, move it into those that
require it (only PID) and keep track in the core code of which
rate was last used for reporting to userspace and the mesh MLME.

There really is no need, at worst ieee80211_start_tx_ba_session
will log a message when debugging is enabled, and poking such
internals of mac80211 definitely doesn't belong into an RC
algorithm.

Subject: iwlwifi: remove HT flags from RXON when not in HT anymore

This patch removes the HT flags from RXON when moving from HT to legacy.
This avoids keeping those flags set and possibly miss configuring firmware.

If we are configured in HT, fat channel: channel 1 above, and move later
to legacy channel 11, we need to clear the FAT channel control flags in
RXON. If we don't, the firmware will understand this as channel 11 above
which is not possible due to regulatory constraints, leading to firmware
crash.

Subject: mac80211: clean up rate control API

Long awaited, hard work. This patch totally cleans up the rate control
API to remove the requirement to include internal headers outside of
net/mac80211/.

There's one internal use in the PID algorithm left for mesh networking,
we'll have to figure out a way to clean that one up and decide how to
do the peer link evaluation, possibly independent of the rate control
algorithm or via new API.

Additionally, ath9k is left using the cross-inclusion hack for now, we
will add new API where necessary to make this work properly, but right
now I'm not expert enough to do it. It's still off better than before.

Subject: iwlagn: downgrade BUG_ON in interrupt

This BUG_ON really shouldn't trigger, but if it does, as on my machine,
it leaves you wondering what happened because you won't see it. Let's
instead leak a bit of state and memory and at least make it possible to
report it to the kerneloops project to track it.

This patch returns success and empty scan on scans requests that were
rejected because issued too early. The cached bss list from previous
scanning will be returned by mac80211.

From 8cd519e89616057c8a433a54a3e60883e4893017 Mon Sep 17 00:00:00 2001
From: "Winkler, Tomas" <tomas.winkler@intel.com>
Date: Fri, 26 Sep 2008 15:09:32 +0800
Subject: iwlwifi: refactor rx register initialization

The patch adds HW bug W/A FH_RCSR_CHNL0_RX_IGNORE_RXF_EMPTY so that we
can enable again interrupt coalescing. It also uses named constants for
open code.

iwl4965_mac_config internally after scan completed.

It's called anyway from the mac80211 ieee80211_scan_completed():

	if (local->hw_scanning) {
		local->hw_scanning = false;
		if (ieee80211_hw_config(local))
		...
