Merge tag 'mac80211-next-for-davem-2016-09-16' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
