mac80211: disable uAPSD if all ACs are under ACM
It's unlikely that an AP requires WMM mandatory admission control for all access categories, and if it does then we still transmit on the background AC without requesting admission. However, avoid using uAPSD in this case since the implementation could run into issues and might use other ACs etc. Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
