424749c75d ath9k: perform ANI cycle in idle state
As of now the ANI cycle is executed only when the chip is awake.
On idle state case, the station wakes up from network sleep for
beacon reception. Since most of the time, ANI cycle is not syncing
with beacon wakeup, ANI cycle is ignored. Approx 5 mins once, the
calibration is performed. This could affect the connection stability
when the station is idle for long. Even though the OFDM and CCK phy
error rates are too high, ANI is unable to tune its immunity level
as quick enough due to rare execution.

Here the experiment shows that OFDM and CCK levels are at default
even on higher phy error rate.

listenTime=44 OFDM:3 errs=121977/s CCK:2 errs=440818/s ofdm_turn=1

This change ensures that ANI calibration will be exectued atleast
once for every 10 seconds. The below result shows improvements and
immunity levels are adopted quick enough.

listenTime=557 OFDM:4 errs=752/s CCK:4 errs=125/s ofdm_turn=0

b4764c809a carl9170: handle traps from firmware loader
This patch changes the way the driver deals with
command responses and traps which are sent through
the special interrupt input endpoint 3.

While the carl9170 firmware does not use this
endpoint for command responses or traps, the
firmware loader on the device does. It uses it
to notify the host about 'watchdog triggered'
in case the firmware/hardware has crashed.

Note:
Even without this patch, the driver is still
able to detect the mishap and reset the device.
But previously it did that because the trap
event caused an out-of-order message sequence
number error, which also triggered a reset.
