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.
====================
