Network devices don't appear in /dev. At least not in Linux. Some
other Unix implementations do, i think SunOS used to have an entry in
/dev, but i could be remembering wrongly.

But within the kernel, you generally don't refer to a device by its
/dev/foo name. That is a user space abstraction. In the kernel, each
device in the system has a struct device representing it.
