Johannes Berg <johannes@sipsolutions.net> says:

"It has been a while since my last pull request, so we accumulated
another relatively large set of changes:
 * TDLS off-channel support set from Arik/Liad, with some support
   patches I did
 * custom regulatory fixes from Arik
 * minstrel VHT fix (and a small optimisation) from Felix
 * add back radiotap vendor namespace support (myself)
 * random MAC address scanning for cfg80211/mac80211/hwsim (myself)
 * CSA improvements (Luca)
 * WoWLAN Net Detect (wake on network found) support (Luca)
 * and lots of other smaller changes from many people"
