Merge tag 'mac80211-next-for-net-next-2020-02-14' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
A few big new things:
 * 802.11 frame encapsulation offload support
 * more HE (802.11ax) support, including some for 6 GHz band
 * powersave in hwsim, for better testing

Of course as usual there are various cleanups and small fixes.
====================
