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
