This implementation for the Marvell mv88e6xxx chip series, is based on handling ATU miss violations occurring when packets ingress on a port that is locked. The mac address triggering the ATU miss violation is communicated through switchdev to the bridge module, which adds a fdb entry with the fdb locked flag set. The entry is kept according to the bridges ageing time, thus simulating a dynamic entry.
Note: The locked port must have learning enabled for the ATU miss violation to occur.
