net: bridge: mst: Support setting and reporting MST port states
Make it possible to change the port state in a given MSTI by extending
the bridge port netlink interface (RTM_SETLINK on PF_BRIDGE).The
proposed iproute2 interface would be:
bridge mst set dev <PORT> msti <MSTI> state <STATE>
Current states in all applicable MSTIs can also be dumped via a
corresponding RTM_GETLINK. The proposed iproute interface looks like
this:
$ bridge mst
port msti
vb1 0
state forwarding
100
state disabled
vb2 0
state forwarding
100
state forwarding
The preexisting per-VLAN states are still valid in the MST
mode (although they are read-only), and can be queried as usual if one
is interested in knowing a particular VLAN's state without having to
care about the VID to MSTI mapping (in this example VLAN 20 and 30 are
bound to MSTI 100):
$ bridge -d vlan
port vlan-id
vb1 10
state forwarding mcast_router 1
20
state disabled mcast_router 1
30
state disabled mcast_router 1
40
state forwarding mcast_router 1
vb2 10
state forwarding mcast_router 1
20
state forwarding mcast_router 1
30
state forwarding mcast_router 1
40
state forwarding mcast_router 1
