This patch provides a PMD specific API to get PMD internal data
(internals->if_name).

I think we should avoid PMD specific APIs if possible.

internals->if_name is provided by application, as devargs to af_packet
(iface=..), so app already knows port_id -> if_name mapping.

OR

With rte_eth_dev_info_get() af_packet returns the if_index for
underlying interface, it is possible to use if_indextoname() to get ifname.

Because above methods exists to get if_name, I think this API is not
necessary.
