Figure out a way to stop the calls to "reg" "wifi0" and "virbr0" if they
don't exist.

I feel like the last one is the best way, but I don't know what a
solution could look like....

This really has to be done in userland, where these names are being
invented.  Though I suspect the usual way to check whether an interface
exists would be SIOCGIFINDEX, which calls dev_load()!  An alternate
would be to check whether /sys/class/net/<name> exists, but I seem to
recall that /sys/class is somewhat deprecated.

Of course this will mean pain for users until distributions have
updated to userspace which is doing this, but yeah, this clearly seems
like the best way.  (And the only sane one.)
