RE: [PATCH] mwifiex: Track BA sequence number reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Paul,

Thanks for the patch.

> Some stations reset the sequence number for traffic-ids (TIDs)
> as they initiate a block-ACK session.  In order to detect such
> behavior, mwifiex must note the starting sequence number given
> during the ADDBA request.  If the first received sequence number
> after the ADDBA falls outside the receive window for this TID but
> after the the ADDBA starting sequence number, we can assume that
> this AP has reset its sequence number during the ADDBA.  In this
> case we must adjust the input window backward to incorporate this
> received sequence number instead of ignoring it.  Otherwise, we
> could fail to successfully retrieve an arbitrarily large number
> of downstream frames at the beginning of the block-ACK session.
