There were several issues in the way we were handling the link info coming from firmware. First is the fact that we were carrying around "AUTO" flags to indicate that we needed to populate the values. We can just drop this and assume that we will always be populating the settings from firmware. With this we can also clean up the masking as the "AUTO" flags were just there to be stripped anyway. Second since we are getting rid of the "AUTO" setting we still need a way to report that the link is not configured. We convert the link_mode "AUTO" to "UNKNOWN" to do this. With this we can avoid reporting link up in the phylink_pcs_get_state call as we will just set link to 0 and return without updating the link speed. This is preferred versus the driver just forcing 50G which makes it harder to recover when the FW does start providing valid settings. With this the plan is to eventually replace the link_mode we use with the interface_mode from phylink for all intents and purposes and have the two be interchangeable. At that point we can convert the FW provided settings over to something closer to link partner settings and give phylink greater control of the interface allowing for user override of the settings and an asynchronous setup of the link versus having to pull early settings from firmware.

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.
