mac80211: support S1G association
The changes required for associating in S1G are: - apply S1G BSS channel info before assoc - mark all S1G STAs as QoS STAs - include and parse AID request element - handle new Association Response format - don't fail assoc if supported rates element is missing Signed-off-by: Thomas Pedersen <thomas@adapt-ip.com> Link: https://lore.kernel.org/r/20200922022818.15855-15-thomas@adapt-ip.com [pass skb to ieee80211_add_aid_request_ie(), remove unused variable 'bss'] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
