Possible commit message:
"Invoke move_rstp__() in rstp_port_set_administrative_bridge_port__() if
port is
not initializing.
This was necessary in a test that check that a Port becoming
alternate/backup/disabled stops learning and forwarding.
The move_rstp__() call is necessary to immediatly disable learning and
forwarding on that port.
Without this, the test fails."
Do you have a working copy of this or should I submit a v2?
