commit e086ba2fccda ("e1000e: disable s0ix entry and exit flows for ME systems")
disabled s0ix flows for systems that have various incarnations of the
i219-LM ethernet controller. This was done because of some regressions
caused by an earlier
commit 632fbd5eb5b0e ("e1000e: fix S0ix flows for cable connected case")
with i219-LM controller.
Performing suspend to idle with these ethernet controllers requires a properly
configured system. To make enabling such systems easier, this patch
series offers configuration options to enable/disable the flows.
The flows have also been confirmed to be configured correctly on Dell's Latitude
and Precision CML systems containing the i219-LM controller, when the kernel also
contains the fix for s0i3.2 entry here:
https://lists.osuosl.org/pipermail/intel-wired-lan/Week-of-Mon-20200914/021361.html
Patches 2 and 3 will turn the behavior on by default for Dell's CML systems.
These patches should only be carried if that patch linked above is also applied.
