[dpdk-dev] [PATCH 24/38] net/sfc: handle ingress m-port in EF100 Rx prefix

[Andrew Rybchenko]

From: Igor Romanov <igor.roma...@oktetlabs.ru>

Set ingress mport dynamic field in mbuf in EF100.

For a given PF, Rx queues of representor devices
function on top of the only Rx queue operated by
the PF representor proxy facility. This field is
a means to demultiplex traffic hitting the queue.
