> Commit 161d82de1ff8 ("net: bridge: Notify about !added_by_user FDB
> entries") causes the below oops when bringing up a slave interface,
> because dsa_port_fdb_add is still scheduled, but with a NULL address.
> 
> To fix this, keep the dsa_slave_switchdev_event function agnostic of the
> notified info structure and handle the added_by_user flag in the
> specific dsa_slave_switchdev_event_work function.
