Description:	Ubuntu 16.04 LTS
Release:	16.04

croy-i5-ubuntu% apt-cache policy ethtool
ethtool:
  Installed: 1:4.5-1
  Candidate: 1:4.5-1
  Version table:
 *** 1:4.5-1 500

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

When I suspend to disk I would like to be able to use WOL magic packet
to wake

After explicitly setting the 'g' flag or via /etc/network/interfaces
ethtool shows 'd' after usb resume/wake

I run a dual boot setup with Archlinux. This is not an issue here, WOL
works.

croy-i5-ubuntu% sudo ethtool eno1 | grep Wake
 Supports Wake-on: pumbg
 Wake-on: d

sudo ethtool -s eno1 wol g

croy-i5-ubuntu% sudo ethtool eno1 | grep Wake
 Supports Wake-on: pumbg
 Wake-on: g

systemctl suspend

WOL not working
usb wake

croy-i5-ubuntu% sudo ethtool eno1 | grep Wake

I have followed;

           up ethtool -s eno1 wol g

sudo systemctl restart networking.service
