dsa_port_notify is used to forward an event occuring on a given port, to
all switch chips of a fabric. For example when programming a VLAN on a port,
all ports interconnecting switches together must to programmed too. Even
though mainly switchdev objects or attributes are notified at the moment,
a DSA notification is not specific to switchdev.
