commit 5d872c9f46bd2ea3524af3c2420a364a13667135 upstream.
On some boards with this chip version the BIOS is buggy and misses
to reset the PHY page selector. This results in the PHY ID read
accessing registers on a different page, returning a more or
less random value. Fix this by resetting the page selector first.

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.
