bridge: vlan: add support for mcast_router option
Add support for setting and dumping per-vlan/interface mcast_router
option. It controls the mcast router mode of a vlan/interface pair.
For bridge devices only modes 0 - 2 are allowed. The possible modes
are:
0 - disabled
1 - automatic router presence detection (default)
2 - permanent router
3 - temporary router (available only for ports)
Example:
# mark port ens16 as a permanent mcast router for vlan 100
$ bridge vlan set dev ens16 vid 100 mcast_router 2
# disable mcast router for port ens16 and vlan 200
$ bridge vlan set dev ens16 vid 200 mcast_router 0
$ bridge -d vlan show
port vlan-id
ens16 1 PVID Egress Untagged
state forwarding mcast_router 1
100
state forwarding mcast_router 2
200
state forwarding mcast_router 0
