+Subject: [PATCH] rt2x00: do not increment sequence number while
+ re-transmitting
+
+Currently STA+AP re-transmitting the management frames with
+incremented sequence number if hardware is assigning the sequence.
+
+Fix is to assign the sequence number for Beacon by hardware
+and for other Management frames software will assign the
+sequence number
+
