maybe better to have the following declaration at the beginning
of the method (though not sure it will cause a compilation error
under most compilers)
+
+ const struct rte_pktmbuf_pool_private *mbp_priv =
+ rte_mempool_get_priv(mb_pool);

+nfb_eth_ndp_tx(void *queue,

...

Should be "TX invalid arguments!\n"):
+ if (unlikely(ndp->queue == NULL || nb_pkts == 0)) {
+ RTE_LOG(ERR, PMD, "RX invalid arguments!\n");
