Certain PHY's have issues when operating in GBit slave mode and can be forced to master mode. Examples are RTL8211C, also the Micrel PHY driver has a DT setting to force master mode. If two such chips are link partners the autonegotiation will fail. Standard defines a self-clearing on read, latched-high bit to indicate this error. Check this bit to inform the user.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
