With following patches:
commit 9b01c885be36 ("net: phy: c22: migrate to genphy_c45_write_eee_adv()")
commit 5827b168125d ("net: phy: c45: migrate to genphy_c45_write_eee_adv()")
we set the advertisement to potentially supported values. This behavior
may introduce new regressions on systems where EEE was disabled by
default (BIOS or boot loader configuration or by other ways.)
At same time, with this patches, we would overwrite EEE advertisement
configuration made over ethtool.
To avoid this issues, we need to cache initial and ethtool advertisement
configuration and store it for later use.

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.
