USXGMII supports passing link information in-band between PHY and MAC PCS, add it to the list of protocols that support in-band AN mode. Being a MAC-PHY protocol that can auto-negotiate link speeds up to 10 Gbps, we populate the initial supported mask with the entire spectrum of link modes up to 10G that PHYLINK supports, and we let the driver reduce that mask in its .phylink_validate method.

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.
