So far rpm doesn't cover cases like unused ports which are never
brought up. If they are active at probe time they remain in this state.
Included in this patch:
- Let the idle notification check whether we can suspend and let it
schedule the suspend. This way we don't need to have calls to
pm_schedule_suspend in different places.
- At the end of rtl_open and rtl_init_one send an idle notification
to allow suspending if the link is down. If a cable is plugged in
aneg is finished before the suspend timer expires and the suspend
request is cancelled.
- Change rtl8169_runtime_suspend to power down the chip if the
interface is down.
Successfully tested on a RTL8168evl (mac version 34).
