Subject: [PATCH] rt2x00: do not increment sequence number while
re-transmitting
Currently rt2x00 devices retransmit the management frames with
incremented sequence number if hardware is assigning the sequence.
This is HW bug fixed already for non-QOS data frames, but it should
be fixed for management frames except beacon.
Without fix retransmitted frames have wrong SN:
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1648, FN=0, Flags=........C Frame is not being retransmitted 1648 1
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1649, FN=0, Flags=....R...C Frame is being retransmitted 1649 1
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1650, FN=0, Flags=....R...C Frame is being retransmitted 1650 1
With the fix SN stays correctly the same:
88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=........C
88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=....R...C
88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=....R...C

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
