Ido Schimmel says: ==================== mlxsw: Offload TC action pedit munge dsfield Petr says: The Spectrum switches allow packet prioritization based on DSCP on ingress, and update of DSCP on egress. This is configured through the DCB APP rules. For some use cases, assigning a custom DSCP value based on an ACL match is a better tool. To that end, offload FLOW_ACTION_MANGLE to permit changing of dsfield as a whole, or DSCP and ECN values in isolation. After fixing a commentary nit in patch #1, and mlxsw naming in patch #2, patches #3 and #4 add the offload to mlxsw. Patch #5 adds a forwarding selftest for pedit dsfield, applicable to SW as well as HW datapaths. Patch #6 adds a mlxsw-specific test to verify DSCP rewrite due to DCB APP rules is not performed on pedited packets. The tests only cover IPv4 dsfield setting. We have tests for IPv6 as well, but would like to postpone their contribution until the corresponding iproute patches have been accepted. ==================== Signed-off-by: David S.

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.
