ath5k: delay full calibration after reset

During scans the full calibration usually does not make much sense,
PAPD probing and IQ calibration should be deferred until there is
enough time to complete them. Adding 100 ms to the initial full
calibration delay should be enough to do this.

ath9k_hw: Fix incorrect key_miss handling

Decryping frames on key_miss handling shouldn't be done for Michael
MIC failed frames as h/w would have already decrypted such frames
successfully anyway.

Also leaving CRC and PHY error(where the frame is going to be dropped
anyway), we are left to prcoess Decrypt error for which s/w decrypt is

libertas: fix handling of command timeout, completion and interruption

When commands time out, corruption ensues. As lbs_complete_command()
is called without locking, the command node is mistakenly freed twice.
Also fixed up locking here in a few other places.

The nature of command timeout may be that the card didn't even
acknowledge receipt of the request. Detect this case and reset dnld_sent
so that other commands don't hang forever.

When cmdnodes are moved between the free list and the pending list,
their list heads should be reinitialized. Fixed this.

Sometimes commands are completed without actually submitting them or
removing them from cmdpendingq. We must remember to remove them from
cmdpendingq in these cases, so handle this in lbs_complete_command().

Harmless signals generated during suspend/resume were interrupting
lbs_cmd. Convert to an uninterruptible sleep to avoid this.

lbs_thread must be woken up every time there is some new work to do.
I found that when 2 commands are queued, ther completion of the first
command would not wake up lbs_thread to submit the second. Poke lbs_thread
at the end of lbs_complete_command() to fix this.

iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic state

WiFi throughput drops drastically when BT is turned on, BT and WiFi
are simultaneously transmitting/receiving traffic. This is particularly true
when BT has higher priority over WiFi, and hence the device defers TX frames.
The AP assumes that the channel is bad and reduces the data rate, implying
longer airtime, which exacerbates the problem further, resulting ultimately
in what is popularly called the "death-spiral" phenomenon. The use of PS-poll
in such scenarios guarantees a low but consistent throughput.

Since the death-spiral phenomenon is observed only when the RSSI is low, use
PS-poll only when RSSI is low and disable when high, with a known hysterisis.

This feature specifies the high and low thresholds and implements the
callbacks registered with mac80211, which will be called when threshold events
occur.

mac80211: simplify RX PN/IV handling

The current rx->queue value is slightly confusing.
It is set to 16 on non-QoS frames, including data,
and then used for sequence number and PN/IV checks.
Until recently, we had a TKIP IV checking bug that
had been introduced in 2008 to fix a seqno issue.
Before that, we always used TID 0 for checking the
PN or IV on non-QoS packets.

Go back to the old status for PN/IV checks using
the TID 0 counter for non-QoS by splitting up the
rx->queue value into "seqno_idx" and "security_idx"
in order to avoid confusion in the future. They
each have special rules on the value used for non-
QoS data frames.

Since the handling is now unified, also revert the
special TKIP handling from my patch
