Merge tag 'mac80211-next-for-net-next-2021-10-21' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Quite a few changes:
 * the applicable eth_hw_addr_set() and const hw_addr changes
 * various code cleanups/refactorings
 * stack usage reductions across the wireless stack
 * some unstructured find_ie() -> structured find_element()
   changes
 * a few more pieces of multi-BSSID support
 * some 6 GHz regulatory support
 * 6 GHz support in hwsim, for testing userspace code
 * Light Communications (LC, 802.11bb) early band definitions
   to be able to add a first driver soon

* tag 'mac80211-next-for-net-next-2021-10-21' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next: (35 commits)
  cfg80211: fix kernel-doc for MBSSID EMA
  mac80211: Prevent AP probing during suspend
  nl80211: Add LC placeholder band definition to nl80211_band
  ...
