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 Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David Ahern <dsahern@kernel.org>
