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
