Subject[PATCH net] net: dsa: mv88e6xxx: override existent unicast portvec in port_fdb_add
Date
Having multiple destination ports for a unicast address does not make
sense.
Make port_db_load_purge override existent unicast portvec instead of
adding a new port bit.

Fixes: 884729399260 ("net: dsa: mv88e6xxx: handle multiple ports in ATU")
