Merge tag 'mac80211-next-for-davem-2015-12-07' into next
This pull request got a bit bigger than I wanted, due to
needing to reshuffle and fix some bugs. I merged mac80211
to get the right base for some of these changes.
* new mac80211 API for upcoming driver changes: EOSP handling,
key iteration
* scan abort changes allowing to cancel an ongoing scan
* VHT IBSS 80+80 MHz support
* re-enable full AP client state tracking after fixes
* various small fixes (that weren't relevant for mac80211)
* various cleanups
