bridge: vlan: Allow setting VLAN neighbor suppression state
Add a new VLAN attribute that allows user space to set the neighbor
suppression state of the port VLAN. Example:
# bridge -d -j -p vlan show dev swp1 vid 10 | jq '.[]["vlans"][]["neigh_suppress"]'
false
# bridge vlan set vid 10 dev swp1 neigh_suppress on
# bridge -d -j -p vlan show dev swp1 vid 10 | jq '.[]["vlans"][]["neigh_suppress"]'
true
# bridge vlan set vid 10 dev swp1 neigh_suppress off
# bridge -d -j -p vlan show dev swp1 vid 10 | jq '.[]["vlans"][]["neigh_suppress"]'
false
# bridge vlan set vid 10 dev br0 neigh_suppress on
Error: bridge: Can't set neigh_suppress for non-port vlans.
