Daniel Machon 246c77f666 net: microchip: sparx5: add support for DSCP rewrite
Add support for DSCP rewrite in Sparx5 driver. On egress DSCP is
rewritten from either classified DSCP, or frame DSCP. Classified DSCP is
determined by the Analyzer Classifier on ingress, and is mapped from
classified QoS class and DP level. Classification of DSCP is by default
enabled for all ports.

It is required that DSCP is trusted for the egress port *and* rewrite
table is not empty, in order to rewrite DSCP based on classified DSCP,
otherwise DSCP is always rewritten from frame DSCP.

classified_dscp = qos_dscp_map[8 * dp_level + qos_class];
if (active_mappings && dscp_is_trusted)
	rewritten_dscp = classified_dscp
else
	rewritten_dscp = frame_dscp

To rewrite DSCP to 20 for any frames with priority 7:

$ dcb apptrust set dev eth0 order dscp
$ dcb rewr add dev eth0 7:20 <-- not in iproute2/dcb yet

README

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.
