Johannes Berg says:

====================
This time we have various things - all across the board:
 * MU-MIMO sniffer support in mac80211
 * a create_singlethread_workqueue() cleanup
 * interface dump filtering that was documented but not implemented
 * support for the new radiotap timestamp field
 * send delBA in two unexpected conditions (as required by the spec)
 * connect keys cleanups - allow only WEP with index 0-3
 * per-station aggregation limit to work around broken APs
 * debugfs improvement for the integrated codel algorithm
and various other small improvements and cleanups.
====================
