In systemd's networkd and udevd, we would like to give the administrator a simple way to filter ethernet devices by their DEVTYPE. In order to avoid having a special treatment of the case where DEVTYPE=(null), initialize it to a default value, "ethernet", in the kernel.

Any comments before I send it off to LKML? I suppose it may make sense to hide this behind a kernel option in case we are worried about breaking existing users (but if ConnMan is adapted, I don't know of any other issues, NetworkManager is not affected at least).
