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
====================
