[ Upstream commit534e7366f4] Ethtool self test contains a test for link speed. This test reads the PTYS register and determines whether the current speed is valid or not. Change current implementation to use the function mlx5e_port_linkspeed() that does the same check and fails when speed is invalid. This code redundancy lead to a bug when mlx5e_port_linkspeed() was updated with expended speeds and the self test was not.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
