Reduce the link parameters after a link training failure for MST outputs, similarly to how this is done for SST. For now allow the reduction only by staying in the 8b/10b vs. 128b/132b mode. Enabling the mode switch is left for a follow-up patchset, after taking measures ensuring that the mode switch happens properly. In particular a rediscovery of the whole MST topology may be required for such a switch, see the References below.

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 reStructuredText 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.
