While testing ethtool with the Methode DM7052 module, it was noticed that attempting to set the advertising mask results in the mask being truncated to the support offered by the currently chosen PHY interface mode. When a PHY dynamically changes the PHY interface mode, limiting the advertising mask in this way is not correct - if the PHY happened to negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we don't want to restrict the advertisement to just 10GBASE-* modes. Rework setting the advertisement to take account of this; do not pass the requested advertisement through phylink_validate(), but rely on the advertisement restriction (supported mask) set when the PHY was initially setup.

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.
