[PATCH net-next v3 04/12] net/mlx5e: Implement ndo_get_port_parent_id()

Florian Fainelli
2019-02-05T23:53:18Z

mlx5e 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().

Since mlx5e makes use of switchdev_port_parent_id() convert it to use
netdev_port_same_parent_id().
