> Currently the system will be woken up via WOL(Wake On Lan) even if the
> device wakeup ability has been disabled via sysfs:
>  cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup
>  disabled
> 
> The system should not be woken up if the user has explicitly
> disabled the wake up ability for this device.
> 
> This patch clears the WOL ability of this network device if the
> user has disabled the wake up ability in sysfs.
