Add basic support for detecting the link and reporting it at the netdev layer. For now we will just use the values reporeted by the firmware as the link configuration and assume that is the current configuration of the MAC and PCS. With this we start the stubbing out of the phylink interface that will be used to provide the configuration interface for ethtool in a future patch set. The phylink interface isn't an exact fit. As such we are currently working around several issues in this patch set that we plan to address in the future such as: 1. Support for FEC 2. Support for multiple lanes to handle 50GbaseR2 vs 50GbaseR1 3.

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.
