Set the transmit RS bit threshold of TX rings to N, where 0 <= N <= value of ``--txd``.
The default value is 0.
-* ``--rx-queue-stats-mapping=(port,queue,mapping)[,(port,queue,mapping)]``
-
- Set the RX queues statistics counters mapping 0 <= mapping <= 15.
-
-* ``--tx-queue-stats-mapping=(port,queue,mapping)[,(port,queue,mapping)]``
-
- Set the TX queues statistics counters mapping 0 <= mapping <= 15.
-
