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
