Heiner Kallweit says: ==================== ethtool: add support for Fast Link Down as new PHY tunable This adds support for Fast Link Down as new PHY tunable. Fast Link Down reduces the time until a link down event is reported for 1000BaseT. According to the standard it's 750ms what is too long for several use cases. This is the kernel-related series, the ethtool userspace extension I'd submit once the kernel part has been applied. v2: - add describing comment in patch 1 ==================== Signed-off-by: David S.

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.
