From: Nikolay Aleksandrov <nikolay@xxxxxxxxxx>
Add tests for the new per-port/vlan mcast_router option, verify that
unknown multicast packets are flooded only to router ports.
TEST: Port vlan 10 option mcast_router default value [ OK ]
TEST: Port vlan 10 mcast_router option changed to 2 [ OK ]
TEST: Flood unknown vlan multicast packets to router port only [ OK ]
