Currently, when a speed can be supported by different number of lanes, the supported link modes bitmask contains only link modes with a single number of lanes. This was done in order to prevent auto negotiation on number of lanes after 50G-1-lane and 100G-2-lanes link modes were introduced. For example, if a port's max width is 4, only link modes with 4 lanes will be presented as supported by that port, so 100G is always achieved by 4 lanes of 25G. After the previous patches that allow selection of the number of lanes, auto negotiation on number of lanes becomes practical. Remove that filtering of the maximum number of lanes supported link modes, so indeed all the supported and advertised link modes will be shown.

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.
