Introduce xdp_features tool in order to test XDP features supported by the NIC and match them against advertised ones. In order to test supported/advertised XDP features, xdp_features must run on the Device Under Test (DUT) and on a Tester device. xdp_features opens a control TCP channel between DUT and Tester devices to send control commands from Tester to the DUT and a UDP data channel where the Tester sends UDP 'echo' packets and the DUT is expected to reply back with the same packet. DUT installs multiple XDP programs on the NIC to test XDP capabilities and reports back to the Tester some XDP stats. Currently xdp_features supports the following XDP features: - XDP_DROP - XDP_ABORTED - XDP_PASS - XDP_TX - XDP_REDIRECT - XDP_NDO_XMIT Co-developed-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Acked-by: Stanislav Fomichev <sdf@google.com> Link: https://lore.kernel.org/r/7c1af8e7e6ef0614cf32fa9e6bdaa2d8d605f859.1675245258.git.lorenzo@kernel.org Signed-off-by: Alexei Starovoitov <ast@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.
