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)
