not sure, rxportconf seems long word we can put some "_" perhaps, and "port"
seems not used in existing data structures but I can't think of anything to
replace it.

Also they are specific to Rx/Tx queues but the values we are adding are not
specific per queue.
But what we are adding is more like:
"struct rte_eth_txmode"
"struct rte_eth_rxmode"
Which are documented as "Rx / Tx features of an Ethernet port" but these are not
part of dev_info.
