Public bug reported:
[Impact]
When ethernet cable is connected, power consumption is quite high under
suspend-to-idle.
[Fix]
Enable s0ix support for e1000e.
[Test]
When ethernet cable is connected, the power consumption is ~2.5w.
After applying the patch, it can be lowered to ~1.8w.
[Regression Potential]
Low. This fix is limited to fairly recent I219 hardwares.
