A proposal for the corresponding iproute2 interface is available here:

Please pardon my ignorance. Is there a user-mode STP protocol application
that supports MSTP, and that you've tested these patches with?
I'd like to give it a try.
I see that Stephen has already pointed you to mstpd in a sibling
message.
It is important to note though, that AFAIK mstpd does not actually
support MSTP on a vanilla Linux system. The protocol implementation is
in place, and they have a plugin architecture that makes it easy for people
to hook it up to various userspace SDKs and whatnot, but you can't use
it with a regular bridge.
A colleague of mine has been successfully running a modified version of
mstpd which was tailored for v1 of this series (RFC). But I do not
believe he has had the time to rework it for v2. That should mostly be a
matter of removing code though, as v2 allows you to manage the MSTIs
directly, rather than having to translate it to an associated VLAN.
Hello,
we experimented with mstpd with pretty reasonable kernel modifications. Vanilla kernel wasn't capable of transferring the correct mapping from mstpd to the hardware due to lack of vlan2msti mapping and per-msti port state (rather than just per-vlan port state).

I didn't pursue this for a while, though.

Pavel
