Hi Bruce,
This patch changes the behavior and causes some existing code to
malfunction, e.g. bond_ethdev_stop() will get stuck here:
while (rte_ring_dequeue(port->rx_ring, &pkt) != -ENOENT)
rte_pktmbuf_free(pkt);
Another example in test/test/virtual_pmd.c: virtual_ethdev_stop().

Hey Konstantin,
This method does reduce code size but lead to significant performance drop.
I think we need to keep the original code.
