Subject: [PATCH] e1000e: Do not wake up the system via WOL if device wakeup is
disabled
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.

Conflict was because we don't have c8744f44aeae ("e1000e: Add Support
for CannonLake") on 4.9 and 4.4. I've worked around that and queued this
patch for both of those branches.
