Bug description:
[Impact]
System only can reach PC3, and it affects power consumption alot.
[Fix]
Kaiheng implemented a dynamic ASPM for r8169, it not only fixes the PC state
issue, but also fixes network speed issue.
https://patchwork.ozlabs.org/project/linux-pci/cover/20211007161552.272771-1-kai.heng.f...@canonical.com/
[Test]
Verified on 2 different systems which has PC state issue and has network
speed issue, these patches fix both issues.
[Where problems could occur]
It toggles ASPM on and off depends on the network traffic during runtime, I
don't think it'll lead to any regressions. Some potential issues have been
addressed during the patch submitting. It's v6 now and accepted by upstream.
