The Vitesse/Microsemi/Microchip family of switches supported by the Felix DSA driver is capable of selecting between the native tagging protocol and ocelot-8021q. This is necessary to enable flow control on the CPU port. Certain systems where these switches are integrated use the switch as a port multiplexer, so the termination throughput is paramount. Changing the tagging protocol at runtime is possible for these systems, but since it is known beforehand that one tagging protocol will provide strictly better performance than the other, just allow them to specify the preference in the device tree.

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.
