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.
