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).
