An alias like this has no place being supported by the kernel.

Any model for names associated with network interfaces must
revolve around the same name being used on output as on input.

Whether it be virtual devices, device layering, cloned devices
or real devices, there should be only one name that is used for
it on both command lines, inputs and outputs.

The addition of extra names or aliases that are used in some
circumstances and not others complicates the interfaces for
NetBSD rather than makes them simpler and easier to use.
