+Subject: [PATCH] mac80211: mask nested A-MSDU support for mesh
+
+mac80211 incorrectly processes A-MSDUs contained in A-MPDU frames. This
+results in dropped packets and severely impacted throughput.
+
+As a workaround, don't indicate support for A-MSDUs contained in
+A-MPDUs. This improves throughput over mesh links by factor 10.
