Public bug reported:

[Impact]
e1000e devices stop working after s2idle resume.

[Fix] 
Revert the offending patch series, which is to bring some minor power
saving.
 
[Test]
Vendor did extensive tests and didn't find any regression, and the power
consumption remains the same.

[Where problems could occur]
Maybe on some system the series can save some energy, so reverting will
cause some power consumption increase.
