Subject: [PATCH net v2] docs: fix info about representor identification

Update the "How are representors identified?" documentation
subchapter. For newer kernels driver developers should use
SET_NETDEV_DEVLINK_PORT instead of ndo_get_devlink_port()
callback.

- targeting -net, without IWL

 The representor netdevice should *not* directly refer to a PCIe device (e.g.
 through ``net_dev->dev.parent`` / ``SET_NETDEV_DEV()``), either of the
 representee or of the switchdev function.
-Instead, it should implement the ``ndo_get_devlink_port()`` netdevice op, which
-the kernel uses to provide the ``phys_switch_id`` and ``phys_port_name`` sysfs

+Instead, driver developers should use ``SET_NETDEV_DEVLINK_PORT`` macro to
+assign devlink port instance to a netdevice before it registers the netdevice.
+(Some legacy drivers implement ``ndo_get_port_parent_id()`` and
 ``ndo_get_phys_port_name()`` directly, but this is deprecated.)  See
 :ref:`Documentation/networking/devlink/devlink-port.rst <devlink_port>` for the
 details of this API.
