Linux kernel source tree
066d49c199
This is modeled similar to how software steering works: - a reference-counted matcher is maintained for each combination of nat/no_nat x ipv4/ipv6 x tcp/udp/gre. - adding a rule involves finding+referencing or creating a corresponding matcher, then actually adding a rule. - updating rules is implemented using the bwc_rule update API, which can change a rule's actions without touching the match value. By using a T-Rex traffic generator to initiate multi-million UDP flows per second, a kernel running with these patches on the RX side was able to offload ~600K flows per second, which is about ~7x larger than what software steering could do on the same hardware (256-thread AMD EPYC, 512 GB RAM, ConnectX-7 b2b).

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 reStructuredText 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.
