station is associated.
Smart Fifo allows aggragations of DMA transactions and by that
causes processor and memory controller to stay for a longer time
on lower c-states, thus saving platform power.
Firmware relies on driver to activate and disable it.

nl80211: add VHT support for set_bitrate_mask
Add VHT MCS/NSS set support for nl80211_set_tx_bitrate_mask().
This should be used mainly for test purpose, to check
different MCS/NSS VHT combinations.

mac80211: align ieee80211_ibss_csa_beacon() with ieee80211_assign_beacon()
The return value of ieee80211_ibss_csa_beacon is not aligned with the
return value of ieee80211_assign_beacon(). For consistency and to be
able to use both functions with similar code, change
ieee80211_ibss_csa_beacon() not to send the bss changed notification
itself, but return what has changed so the caller can send the
notification instead.

mac80211: update adjusting TBTT bit in beacon
This regression was introduced in "mac80211: cache mesh
beacon".
mesh_sync_offset_adjust_tbtt() was assuming that the
beacon would be rebuilt in every single pre-tbtt
interrupt, but now the beacon update happens on the
workqueue, and it must be ready for immediate delivery to
the driver.
Save a pointer to the meshconf IE in the beacon_data (this
works because both the IE pointer and beacon buffer are
protected by the same rcu_{dereference,assign_pointer}())
for quick updates during pre-tbtt. This is faster and a
little prettier than iterating over the elements to find
the meshconf IE every time.

ath10k: fix band reporting for mgmt CCK frames on 5GHz
Although CCK modulation isn't expected for 11a if
it happened it made ath10k report wrong band
(2GHz) for a mgmt frame that were actually
received on 5Ghz band. Frequency would also
decoded incorrectly too.
In case of 5GHz-only devices this triggered
mac80211 WARN_ON because there was no according
sband pointer to be found.
The patch should fix delivery of such frames by
using different means to acquire band parameter.
