Public bug reported:
[Impact]
The PC state stays at PC3 if realtek ethernet doesn't enable ASPM.
[Fix]
Discussed with upstream and they would like to use sysfs to toggle the ASPM
link states, but the patches didn't get merged yet, so we merger them as SAUCE
patches.
[Test]
Verified on machines with realtek ethernet device, the ethernet works well and
the system can enter PC10.
[Regression Potential]
High. From upstream maintainer, enable realtek ethernet ASPM may lead to some
serious issue, so regression is expected. Those regression should come from old
realtek chips, we'll make sure all new platforms with realtek NIC have no any
issues.
