Merge tag 'mac80211-next-for-davem-2020-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
This time we have:
* some code to support SAE (WPA3) offload in AP mode
* many documentation (wording) fixes/updates
* netlink policy updates, including the use of NLA_RANGE
with binary attributes
* regulatory improvements for adjacent frequency bands
* and a few other small additions/refactorings/cleanups
====================
