Rather than having a single define for maximum queues per ethernet port,
we can set the max values for Rx queues and Tx queue independently. This
allows future memory saving for apps which only need large numbers of Rx
queues or only large numbers of Tx queues.

=======================================================
+* **New configuration settings for Rx and Tx Ethernet Queues.**
+
+ New defines have been added to DPDK to allow independent tracking of the maximum number of Rx and Tx queues.
+ These defines as ``RTE_MAX_ETHPORT_RX_QUEUES`` and ``RTE_MAX_ETHPORT_TX_QUEUES``,
+ and should be used in place of the older macro ``RTE_MAX_QUEUES_PER_PORT``.
