sfc: use a dynamic m-port for representor RX and set it promisc
Representors do not want to be subject to the PF's Ethernet address filters, since traffic from VFs will typically have a destination either elsewhere on the link segment or on an overlay network. So, create a dynamic m-port with promiscuous and all-multicast filters, and set it as the egress port of representor default rules. Since the m-port is an alias of the calling PF's own m-port, traffic will still be delivered to the PF's RXQs, but it will be subject to the VNRX filter rules installed on the dynamic m-port (specified by the v-port ID field of the filter spec).
