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.

This patch changes the way the driver deals with

to notify the host about 'watchdog triggered'

Note:
Even without this patch, the driver is still

But previously it did that because the trap

mac80211: make client powersave independent of interface type
This patch prepares mac80211 for a later implementation of mesh or
ad-hoc powersave clients.
The structures related to powersave (buffer, TIM map, counters) are
moved from the AP-specific interface structure to a generic structure
that can be embedded into any interface type.
The functions related to powersave are prepared to allow easy
extension with different interface types. For example with:
+ } else if (sta->sdata->vif.type == NL80211_IFTYPE_MESH_POINT) {
+ ps = &sdata->u.mesh.ps;
Some references to the AP's beacon structure are removed where they
were obviously not used.

mac80211: introduce channel context skeleton code
Channel context are the foundation for multi-channel
operation. They are are immutable and are re-created
(or re-used if other interfaces are bound to a certain
channel and a compatible channel type) on channel

iwlwifi: first deactivate a queue, then wipe out its data
Doing the opposite is wrong, the SCD wouldn't like someone
to clear its data while the queue is still active.
