There are other things. The user may configure the netdev parameters in
advance, like mtu, put it in a bridge, setup TC filters on it etc.
The linecard unplug/plug does not destroy the settings. This is the same
thing with split ports and that is why we have implemented split ports
in "provision" mode as well.

It it not a device, does not have "struct device" related to it.
It is just a phy part of another device.
