Merge tag 'mac80211-next-for-net-next-2021-12-21' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
This time we have:
* ndo_fill_forward_path support in mac80211, to let drivers use it
* association comeback notification for userspace, to be able
to react more sensibly to long delays
* support for background radar detection hardware in some chipsets
* SA Query Procedures offload on the AP side
* more logging if we find problems with HT/VHT/HE
* various cleanups and minor fixes
