Add extra libefx flags to Rx queue information initialization
function interface to be able to specify the ingress m-port
flag for a representor RxQ. Rx prefix of packets on that queue
will contain ingress m-port field required for packet forwarding

MAE delivers counters data as special packets via dedicated Rx queue.
Reserve an RxQ so that it does not interfere with ethdev Rx queues.

There is no point to reserve the queue if no service cores are
available and counters cannot be used.

There is no update in header content and since ethdev.h included by

logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
