It appears that the driver still transmits in CTS protect mode even though it is not enabled in mac80211. That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect. The only difference between them GA does not use B rates. Find if only B rate in GB or GA in protect mode otherwise transmit packets as PK_TYPE_11A.
