+Subject: [PATCH] mac80211: exclude multicast packets from AQL pending airtime
+
+In AP mode, multicast traffic is handled very differently from normal traffic,
+especially if at least one client is in powersave mode.
+This means that multicast packets can be buffered a lot longer than normal
+unicast packets, and can eat up the AQL budget very quickly because of the low
+data rate.
+Along with the recent change to maintain a global PHY AQL limit, this can lead
+to significant latency spikes for unicast traffic.
+
+Since queueing multicast to hardware is currently not constrained by AQL limits
+anyway, let's just exclude it from the AQL pending airtime calculation entirely.
+
+Fixes: 8e4bac067105 ("wifi: mac80211: add a per-PHY AQL limit to improve fairness")
