ack, but patch adds two places that updates the 'err_pkts'. One of them is where
mbuf allocation failed, and for this case there is a specific stats field,
'rx_nombuf'. Can you please update the patch to use this field?

PMD Tx shouldn't free mbufs that are not sent, it is application's
responsibility to free (or resend, or whatever application wants).
Please drop this part of the patch.
