When ADQ queue groups (TCs) are created via tc mqprio command, RSS contexts and associated RSS indirection tables are configured automatically per TC based on the queue ranges specified for each traffic class. For ex: tc qdisc add dev enp175s0f0 root mqprio num_tc 3 map 0 1 2 \ queues 2@0 8@2 4@10 hw 1 mode channel will create 3 queue groups (TC 0-2) with queue ranges 2, 8 and 4 in 3 queue groups. Each queue group is associated with its own RSS context and RSS indirection table. Add support to expose RSS indirection tables for all ADQ queue groups using ethtool RSS contexts interface. ethtool -x enp175s0f0 context <tc-num> Signed-off-by: Sridhar Samudrala <sridhar.samudrala@intel.com> Signed-off-by: Sudheer Mogilappagari <sudheer.mogilappagari@intel.com> Tested-by: Bharathi Sreenivas <bharathi.sreenivas@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Link: https://lore.kernel.org/r/20220512213249.3747424-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
