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. > >> do.

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