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.
