sfc: determine wire m-port at EF100 PF probe time
Traffic delivered to the (MAE admin) PF could be from either the wire
or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these;
base_mport is the value this field will have for traffic from the wire
(which should be delivered to the PF's netdevice, not a representor).
