[iproute2,0/3] Multiple Spanning Tree (MST) Support

Message

Tobias Waldekranz June 14, 2024, 1:38 p.m. UTC

This series adds support for:

- Enabling MST on a bridge:

      ip link set dev <BR> type bridge mst_enable 1

- (Re)associating VLANs with an MSTI:

      bridge vlan global set dev <BR> vid <X> msti <Y>

- Setting the port state in a given MSTI:

      bridge mst set dev <PORT> msti <Y> state <Z>

- Listing the current port MST states:

      bridge mst show

NOTE: Multiple spanning tree support was added to Linux a couple of
years ago[1], but the corresponding iproute2 patches were never
posted. Mea culpa. Yesterday this was brought to my attention[2],
which is why you are seeing them today.
