Merge tag 'mac80211-next-for-davem-2018-12-19' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
This time we have too many changes to list, highlights:
* virt_wifi - wireless control simulation on top of
another network interface
* hwsim configurability to test capabilities similar
to real hardware
* various mesh improvements
* various radiotap vendor data fixes in mac80211
* finally the nl_set_extack_cookie_u64() we talked
about previously, used for
* peer measurement APIs, right now only with FTM
(flight time measurement) for location
* made nl80211 radio/interface announcements more complete
* various new HE (802.11ax) things:
updates, TWT support, ...
====================
