====================
address EEE regressions on KSZ switches since v6.9 (v6.14+)
This patch series addresses a regression in Energy Efficient Ethernet
(EEE) handling for KSZ switches with integrated PHYs, introduced in
kernel v6.9 by commit fe0d4fd928 ("net: phy: Keep track of EEE
configuration").
The first patch updates the DSA driver to allow phylink to properly
manage PHY EEE configuration. Since integrated PHYs handle LPI
internally and ports without integrated PHYs do not document MAC-level
LPI support, dummy MAC LPI callbacks are provided.
The second patch removes outdated EEE workarounds from the micrel PHY
driver, as they are no longer needed with correct phylink handling.
This series addresses the regression for mainline and kernels starting
from v6.14. It is not easily possible to fully fix older kernels due
to missing infrastructure changes.
Tested on KSZ9893 hardware.

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 reStructuredText 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.
