+Subject: [PATCH] ath9k_hw: avoid setting cwmin/cwmax to 0 for IBSS for AR9003
+
+IBSS requires the cwmin and cwmax to be respected when
+we reset the txqueues on AR9003 otherwise the distribution
+of beacons will be balanced towards the AR9003 card first
+preventing equal contention for air time for other peers
+on the IBSS.
+
+Without this IBSS will work but only the AR9003 card will be
+be issuing beacons on the IBSS.
