[PATCH net-next v3 03/12] liquidio: Implement ndo_get_port_parent_id()

Florian Fainelli
2019-02-05T23:53:17Z

Liquidio only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it
a great candidate to be converted to use the ndo_get_port_parent_id()
NDO instead of implementing switchdev_port_attr_get().
