bridge: vlan: Add support for neigh_suppress option
Add support for the per-VLAN neigh_suppress option. Example:
# bridge vlan set vid 10 dev swp1 neigh_suppress on
# bridge -d -j -p vlan show dev swp1 vid 10
[ {
"ifname": "swp1",
"vlans": [ {
"vlan": 10,
"state": "forwarding",
"mcast_router": 1,
"neigh_suppress": true
} ]
} ]
# bridge -d vlan show dev swp1 vid 10
port vlan-id
swp1 10
state forwarding mcast_router 1 neigh_suppress on
# bridge vlan set vid 10 dev swp1 neigh_suppress off
# bridge -d -j -p vlan show dev swp1 vid 10
[ {
"ifname": "swp1",
"vlans": [ {
"vlan": 10,
"state": "forwarding",
"mcast_router": 1,
"neigh_suppress": false
} ]
} ]
# bridge -d vlan show dev swp1 vid 10
port vlan-id
swp1 10
state forwarding mcast_router 1 neigh_suppress off
