Ido Schimmel says: ==================== mlxsw: Add support for egress and policy-based sampling So far mlxsw only supported ingress sampling using matchall classifier. This series adds support for egress sampling and policy-based sampling using flower classifier on Spectrum-2 and newer ASICs. As such, it is now possible to issue these commands: # tc filter add dev swp1 egress pref 1 proto all matchall action sample rate 100 group 1 # tc filter add dev swp2 ingress pref 1 proto ip flower dst_ip 198.51.100.1 action sample rate 100 group 2 When performing egress sampling (using either matchall or flower) the ASIC is able to report the end-to-end latency which is passed to the psample module. Series overview: Patches #1-#3 are preparations without any functional changes Patch #4 generalizes the idea of sampling triggers and creates a hash table to track active sampling triggers in preparation for egress and policy-based triggers. The motivation is explained in the changelog Patch #5 flips mlxsw to start using this hash table instead of storing ingress sampling triggers as an attribute of the sampled port Patch #6 finally adds support for egress sampling using matchall classifier Patches #7-#8 add support for policy-based sampling using flower classifier Patches #9 extends the mlxsw sampling selftest to cover the new triggers Patch #10 makes sure that egress sampling configuration only fails on Spectrum-1 ==================== 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.
