Vladimir Oltean says: ==================== Basic QoS classification on Felix DSA switch using dcbnl Basic QoS classification for Ocelot switches means port-based default priority, DSCP-based and VLAN PCP based. This is opposed to advanced QoS classification which is done through the VCAP IS1 TCAM based engine. The patch set is a logical continuation of this RFC which attempted to describe the default-prio as a matchall entry placed at the end of a series of offloaded tc filters: https://patchwork.kernel.org/project/netdevbpf/cover/20210113154139.1803705-1-olteanv@gmail.com/ I have tried my best to satisfy the feedback that we should cater for pre-configured QoS profiles. Ironically, the only pre-configured QoS profile that the Felix switch driver has is for VLAN PCP (1:1 mapping with QoS class), yet IEEE 802.1Q or dcbnl offer no mechanism for reporting or changing that. Testing was done with the iproute2 dcb app. The qos_class of packets was dumped from net/dsa/tag_ocelot.c. (1) $ dcb app show dev swp3 default-prio 0 (2) $ dcb app replace dev swp3 default-prio 3 (3) $ dcb app replace dev swp3 dscp-prio CS3:5 (4) $ dcb app replace dev swp3 dscp-prio CS2:2 (5) $ dcb app show dev swp3 default-prio 3 dscp-prio CS2:2 CS3:5 Traffic sent with "ping -Q 64 <ipaddr>", which means CS2. These packets match qos_class 0 after command (1), qos_class 3 after command (2), qos_class 3 after command (3), and qos_class 2 after command (2). ==================== 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.
