The majority of DSA drivers do not make use of the PCS support, and thus operate in legacy mode. In order to preserve this behaviour in future, we need to set the legacy_pre_march2020 flag so phylink knows this may require the legacy calls. There are some DSA drivers that do make use of PCS support, and these will continue operating as before - legacy_pre_march2020 will not prevent split-PCS support enabling the newer phylink behaviour.

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.
