The Ocelot switchdev driver and the Felix DSA one need it for different reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is integrated with the traditional NXP Layerscape PCS design which does not support runtime configuration of SerDes protocol. So it needs to pre-validate the phy-mode from the device tree and prevent PHYLINK from attempting to change it. For this, it needs to cache it in a private variable.

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.
