Johannes Berg says:

====================
For 4.11, we seem to have more than in the past few releases:
 * socket owner support for connections, so when the wifi
   manager (e.g. wpa_supplicant) is killed, connections are
   torn down - wpa_supplicant is critical to managing certain
   operations, and can opt in to this where applicable
 * minstrel & minstrel_ht updates to be more efficient (time and space)
 * set wifi_acked/wifi_acked_valid for skb->destructor use in the
   kernel, which was already available to userspace
 * don't indicate new mesh peers that might be used if there's no
   room to add them
 * multicast-to-unicast support in mac80211, for better medium usage
   (since unicast frames can use *much* higher rates, by ~3 orders of
   magnitude)
 * add API to read channel (frequency) limitations from DT
 * add infrastructure to allow randomizing public action frames for
   MAC address privacy (still requires driver support)
 * many cleanups and small improvements/fixes across the board
====================
