PHY devices such as the Marvell Alaska 88E2110 does not return a valid PHY ID when probed using Clause-22. The current implementation treats PHY ID of zero as a non-error and valid PHY ID, and causing the PHY device failed to bind to the Marvell driver. For such devices, we do an additional probe in the Clause-45 space, if a valid PHY ID is returned, we then proceed to attach the PHY device to the matching PHY ID driver.

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.
