Symptom: If invalid configuration is committed when attempting to change STP mode from MSTP to PVRST, the standby pvstag-io process may restart repeatedly. Conditions: Although the exact conditions are not yet known, this has been seen when removing MSTP configuration and adding PVRST configuration in a single commit. This issue is only seen when both the MSTP configuration and PVRST configuration involved Bundle-Ethernet interfaces.
