So the good news is the above two have made it into (the recently-released) 6.9!

Now I'm rooting for these last three:

> 1a0102a08f20 UBUNTU: SAUCE: PCI/ASPM: Enable ASPM for links under VMD domain
> 47c7bfd31514 UBUNTU: SAUCE: PCI/ASPM: Enable LTR for endpoints behind VMD
> 154d48da2c57 UBUNTU: SAUCE: vmd: fixup bridge ASPM by driver name instead

Applying (refactored for 6.8+ versions) of these last three enable full power
savings for 6.9 .

        -Kenny, fingers crossed
