LPDUs that the link station may have unacknowledged at any given time.

The RW parameter specifies the maximum number of unacknowledged sequentially
numbered I-format LPDUs that the link station can receive from the remote link station.

should set its effective TW to a value less than or equal to the value of the received
RW to avoid overruns.
