All devices are capable of using regular DSA tags. Support for Ethertyped DSA tags sort into three categories: 1. No support. Older chips fall into this category. 2. Full support. Datasheet explicitly supports configuring the CPU port to receive FORWARDs with a DSA tag. 3. Undocumented support. Datasheet lists the configuration from category 2 as "reserved for future use", but does empirically behave like a category 2 device. So, instead of listing the one true protocol that should be used by a particular chip, specify the level of support for EDSA (support for regular DSA is implicit on all chips). As before, we use EDSA for all chips that fully supports it. In upcoming changes, we will use this information to support dynamically changing the tag protocol.

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.
