    I think in that case we'd probably just want the interface to be downed?
    Some of this is going to require device-specific policy, I think - for
    the network case we probably want something in between IF_RUNNING and
    IF_DOWN (IF_CARRIER, perhaps) that indicates that we want the PHY to be
    powered. Pushing this out to sysfs would mean we'd have a consistent
    interface but varying semantics, and I'm not convinced that's an
    especially helpful interface.
