+Subject: [PATCH] ath9k_hw: fix hardware queue allocation
+
+The driver passes the desired hardware queue index for a WMM data queue
+in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which
+instead relied on the order in which the function is called.

+Subject: [PATCH] ath9k: fix BE/BK queue order
+
+Hardware queues are ordered by priority. Use queue index 0 for BK, which
+has lower priority than BE.
