Merge tag 'mac80211-next-for-net-next-2020-11-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Some updates:
 * injection/radiotap updates for new test capabilities
 * remove WDS support - even years ago when we turned
   it off by default it was already basically unusable
 * support for HE (802.11ax) rates for beacons
 * support for some vendor-specific HE rates
 * many other small features/cleanups

* tag 'mac80211-next-for-net-next-2020-11-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next: (21 commits)
