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 ... ==================== Link: https://lore.kernel.org/r/20211021154953.134849-1-johannes@sipsolutions.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
