Hi Vladimir,
maybe you have missed my upstreaming of this patch set...

According to our earlier discussions I have now implemented the
feature, so that the ATU locked entries are owned by the driver, so to
make the entries dynamic I add the entries to a list and use kernel
timers to age out the entries as they should be 'dynamic'. See
mv88e6xxx_switchdev.c.

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.
