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, ...
====================
