Do you know what dhcpcd needs it for? If it's just automatic binding
when you don't specify an interface, that's probably a bad idea
anyway... But maybe we should support it.

I didn't really "review" it, but as long as you tested it, it's

infinite family of them, so as long as each of the 3 works for you
it should be fine.
