why eth0 not in /dev

why eth0 not in /dev

[zzs]

When barebox starts, devinfo can show eth0's info
like this

9200-EK:/dev devinfo eth0
resources:
driver: none
bus: platform

Parameters:
          ipaddr = 192.168.0.109
         ethaddr =
         gateway =
         netmask =
        serverip =

But I can't see it in /dev, Why?

Files are registered manually under /dev/ by device drivers when they
want to provide a file there. A network device does not have anything
useful to register as a file, so there is none. Files under /dev/ often
have the same name as the devices, but this does not have to be the
case, they are two different things.
