Subject: [PATCH v2 4/4] testpmd: make use of per-PMD TxRx parameters

The optimal values of several transmission & reception related
parameters, such as burst sizes, descriptor ring sizes, and number
of queues, varies between different network interface devices. This
patch allows testpmd to make use of per-PMD tuned parameter values.
