It is different with Windows. The Windows would resume the device before
system suspend, if the system suspend follows the autosuspend.

Would this be a problem? After system suspend, the device may wake up
the system when receiving any packet, not only magic packet. The wake
events are different for system suspend and autosuspend. However, I
couldn't change the wake event, because the autosuspend occurs first,
and the suspend() is only called once.
