https://patchwork.ozlabs.org/project/intel-wired-lan/patch/[email protected]/
[Test]
Verified on the target machine, and confirmed the issue is gone.
[Where problems could occur]
The impact is low, it keeps the GPT clock enabled for CSME when
e1000e_pm_resume() is called. I can't see this may introduce any regression.
