====================
octeontx2-pf: HTB offload support
octeontx2 silicon and CN10K transmit interface consists of five
transmit levels starting from MDQ, TL4 to TL1. Once packets are
submitted to MDQ, hardware picks all active MDQs using strict
priority, and MDQs having the same priority level are chosen using
round robin. Each packet will traverse MDQ, TL4 to TL1 levels.
Each level contains an array of queues to support scheduling and
shaping.
As HTB supports classful queuing mechanism by supporting rate and
ceil and allow the user to control the absolute bandwidth to
particular classes of traffic the same can be achieved by
configuring shapers and schedulers on different transmit levels.
This series of patches adds support for HTB offload,
Patch1: Allow strict priority parameter in HTB offload mode.
Patch2: Rename existing total tx queues for better readability
Patch3: defines APIs such that the driver can dynamically initialize/
deinitialize the send queues.
Patch4: Refactors transmit alloc/free calls as preparation for QOS
offload code.
Patch5: moves rate limiting logic to common header which will be used
by qos offload code.
Patch6: Adds actual HTB offload support.
Patch7: exposes qos send queue stats over ethtool.
Patch8: Add documentation about htb offload flow in driver

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.
