Merge tag 'mac80211-next-for-davem-2020-05-31' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Another set of changes, including
 * many 6 GHz changes, though it's not _quite_ complete
   (I left out scanning for now, we're still discussing)
 * allow userspace SA-query processing for operating channel
   validation
 * TX status for control port TX, for AP-side operation
 * more per-STA/TID control options
 * move to kHz for channels, for future S1G operation
 * various other small changes
====================
