This patch adds AF_XDP selftests framework under selftests/bpf.
Topology:
---------
----------- -----------
| xskX | --------- | xskY |
----------- | -----------
| | |
----------- | ----------
| vethX | --------- | vethY |
----------- peer ----------
| | |
namespaceX | namespaceY
Prerequisites setup by script test_xsk.sh:
Set up veth interfaces as per the topology shown ^^:
* setup two veth interfaces and one namespace
** veth<xxxx> in root namespace
** veth<yyyy> in af_xdp<xxxx> namespace
** namespace af_xdp<xxxx>
* create a spec file veth.spec that includes this run-time configuration
*** xxxx and yyyy are randomly generated 4 digit numbers used to avoid
conflict with any existing interface
* tests the veth and xsk layers of the topology

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.
