Johannes Berg says:

====================
For the 4.7 cycle, we have a number of changes:
 * Bob's mesh mode rhashtable conversion, this includes
   the rhashtable API change for allocation flags
 * BSSID scan, connect() command reassoc support (Jouni)
 * fast (optimised data only) and support for RSS in mac80211 (myself)
 * various smaller changes
====================
