net/sfc: handle ingress mport in EF100 Rx prefix

Browse Source 
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.
