Johannes Berg <johannes@sipsolutions.net> says:

"This relatively large batch of changes is comprised of the
following:
 * large mac80211-hwsim changes from Ben, Jukka and a bit myself
 * OCB/WAVE/11p support from Rostislav on behalf of the Czech Technical
   University in Prague and Volkswagen Group Research
 * minstrel VHT work from Karl
 * more CSA work from Luca
 * WMM admission control support in mac80211 (myself)
 * various smaller fixes, spelling corrections, and minor API additions"
