Merge tag 'mac80211-next-for-net-next-2020-09-21' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
This time we have:
 * some AP-side infrastructure for FILS discovery and
   unsolicited probe resonses
 * a major rework of the encapsulation/header conversion
   offload from Felix, to fit better with e.g. AP_VLAN
   interfaces
 * performance fix for VHT A-MPDU size, don't limit to HT
 * some initial patches for S1G (sub 1 GHz) support, more
   will come in this area
 * minor cleanups
====================
