When the user runs:
bridge link set dev $br_port mcast_flood on

this command should affect not only L2 multicast, but also IPv4 and IPv6
multicast.

In the Ocelot switch, unknown multicast gets flooded according to
different PGIDs according to its type, and PGID_MC only handles L2
multicast. Therefore, by leaving PGID_MCIPV4 and PGID_MCIPV6 at their
default value of 0, unknown IP multicast traffic is never flooded.
