Not currently.

Yes, I can understand that. Technically (per the IBA spec), the SM is
the only one allowed to do Sets. I think it would be possible to have a
diag command do this as long as the MKey protection is weak (which it is
now). A better way might be to have a CLI on the OpenSM and be able to
issue a down command to a port.
