Unless they changed their mind, upstream busybox won't accept it, so it
has to be a patch in OE. But feel free to try to upstream it.

For completeness, this is not some theoretical issue, always calling if up
directly after a network device is discovered does cause issues and is
against spec as well.

The sed stuff isn't that complicated, is it?
