Hi Jun, not sure if I get the point here, as ovs_vport_name() translates into
vport->dev->name.
So are we trying to catch the interface rename between the dev_get_by_name(),
and the code below? This rename could happen at any other place, so this check
does not guarantee anything. Or am I missing something?
