Heiner Kallweit says: ==================== net: phy: improve and simplify phylib state machine This patch series is based on two axioms: - During autoneg a PHY always reports the link being down - Info in clause 22/45 registers doesn't allow to differentiate between these two states: 1. Link is physically down 2. A link partner is connected and PHY is autonegotiating In both cases "link up" and "aneg finished" bits aren't set. One consequence is that having separate states PHY_NOLINK and PHY_AN isn't needed. By using these two axioms the state machine can be significantly simplified. ==================== 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.
