As stated by Russel King, miic_config() can be called as a result of ethtool setting the configuration while the link is already up. Since the speed is also set in this function, it could potentially modify the current speed that is set. This will only happen if there is no PHY present and we aren't using fixed-link mode. Handle that by storing the current interface mode in the miic_port structure and update the speed only if the interface mode is going to be changed.

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.
