Currently the ethtool shows that WOL(Wake On Lan) is enabled
even if the device wakeup ability has been disabled via sysfs:
cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup
disabled
ethtool eno1
...
Wake-on: g
Fix this in ethtool to check if the user has explicitly disabled the
wake up ability for this device.
