Other than the fact that the carrier flag on wireless devices is kind of
useless, it's fine. I guess it would be somewhat useful if we could
ensure that the carrier would be on _only_ when the card was
successfully associated and authenticated to the requested AP, but until
every driver was converted properly it would be useless because you
couldn't depend on it.
