So far the two functions consider neither member eee_enabled nor eee_active. Therefore network drivers have to do this in some kind of glue code. I think this can be avoided. Getting EEE parameters: When not advertising any EEE mode, we can't consider EEE to be enabled. Therefore interpret "EEE enabled" as "we advertise at least one EEE mode". It's similar with "EEE active": interpret it as "EEE modes advertised by both link partner have at least one mode in common". Setting EEE parameters: If eee_enabled isn't set, don't advertise any EEE mode and restart aneg if needed to switch off EEE. If eee_enabled is set and data->advertised is empty (e.g. because EEE was disabled), advertise everything we support as default. This way EEE can easily switched on/off by doing ethtool --set-eee <if> eee on/off, w/o any additional parameters. The changes to both functions shouldn't break any existing user. Once the changes have been applied, at least some users can be simplified. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
