mlxsw: reg: Configure RIF to forward IPv4 multicast packets by default
Turn on two bits on the Spectrum RIF configuration: - IPv4 multicast: when a multicast packet arrives on a RIF, send it to go through multicast routes lookup. - IPv4 multicast forwarding enable: when multicast packet arrives on a RIF, allow it to be forwarded by multicast routes. If this bit is not set, multicast packets will go through multicast routing lookup but will be dropped at the egress of the ports.
