The current driver code does not accurately report the supported and advertised link modes. It basically always assumes the media type is copper for any particular speed. Utilize the recently added link mode mappings to accurately report fully qualified ethtool link modes for advertised and supported speeds. If the media type is known, we will report the supported link modes for that media only. If the media is not known, we will report all possible supported link modes. The user can now specify any supported link modes (including NRZ and PAM4) to advertise for autoneg. It used to only accept copper NRZ modes.

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.
