Hi Ming,

IIUC, the pm_runtime is related to the device drivers, so at the first
glance, we should see invocation of the runtime's functions in drivers/*
and arch/*. Adding these calls in the net core, which makes sense at a
certain point, is a bit weird for me.

From my POV, if the drivers have been modified to support the pm_runtime
and this new functionality brought a regression with the ioctl, that
should be fixed in the drivers and not in the core code.

What happens with your patch if we use ethtool on a virtual device like
veth, macvlan, bridge, ... ?

No any effect no matter if these drivers implement runtime PM or not.


Thanks,
