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.

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.

Check the frame control for ieee80211_is_data_qos() is true before
counting the number of tfds can be free, the tfds_in_queue only
increment when ieee80211_is_data_qos() is true before transmit; so it
should only decrement if the type match.
Remove ieee80211_is_data_qos check for frame_ctrl in tx_resp to avoid
invalid information pass from uCode.

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()

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

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.

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.

...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.

The HT extension channel settings require priv->staging_rxon.channel to be
accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel
and thus HT40 could be broken unless another call to iwl_mac_config came in.
This problem was recently introduced by "iwlwifi: Fix to set correct ht
configuration"
The particular setting in which I noticed this was monitor mode:
iwconfig wlan0 mode monitor
ifconfig wlan0 up
./iw wlan0 set channel 64 HT40-
#./iw wlan0 set channel 64 HT40-
tcpdump -i wlan0 -y IEEE802_11_RADIO
would only catch HT40 packets if I issued the IW command twice.
From visual inspection, iwl_set_rxon_channel does not depend on
iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

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.
