  * Each core is assigned a multi-stream, each stream being composed of
  * a RX queue to poll on a RX port for input messages, associated with
- * a TX queue of a TX port where to send forwarded packets.
- * All packets received on the RX queue of index "RxQj" of the RX port "RxPi"
- * are sent on the TX queue "TxQl" of the TX port "TxPk" according to the two
- * following rules:
- * In VT mode,
- *    - TxPk = (RxPi + 1) if RxPi is even, (RxPi - 1) if RxPi is odd
- *    - TxQl = RxQj
- * In non-VT mode,
- *    - TxPk = (RxPi + 1) if RxPi is even, (RxPi - 1) if RxPi is odd
- *    There is a mapping of RxQj to TxQl to be required,and the mapping was implemented
- *    in dcb_rxq_2_txq_mapping function.
+ * a TX queue of a TX port where to send forwarded packets. All RX and
+ * TX queues are mapping to the same traffic class.
+ * If VMDQ and DCB co-exist, each traffic class on different POOLs share
+ * the same core
