Mario Limonciello 6cecf02e77 Revert "e1000e: disable s0ix entry and exit flows for ME systems" 
commit e086ba2fcc ("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 changed caused power consumption
regressions on the following shipping Dell Comet Lake based laptops:
* Latitude 5310
* Latitude 5410
* Latitude 5410
* Latitude 5510
* Precision 3550
* Latitude 5411
* Latitude 5511
* Precision 3551
* Precision 7550
* Precision 7750

This commit was introduced because of some regressions on certain Thinkpad
laptops.  This comment was potentially caused by an earlier
commit 632fbd5eb5 ("e1000e: fix S0ix flows for cable connected case").
or it was possibly caused by a system not meeting platform architectural
requirements for low power consumption.  Other changes made in the driver
with extended timeouts are expected to make the driver more impervious to
platform firmware behavior.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
