====================
selftests/bpf: Integrate test_xsk.c to test_progs framework
The test_xsk.sh script covers many AF_XDP use cases. The tests it runs
are defined in xksxceiver.c. Since this script is used to test real
hardware, the goal here is to leave it as it is, and only integrate the
tests that run on veth peers into the test_progs framework.
PATCH 1 extracts test_xsk[.c/.h] from xskxceiver[.c/.h] to make the
tests available to test_progs.
PATCH 2 to 7 fix small issues in the current test
PATCH 8 to 13 handle all errors to release resources instead of calling
exit() when any error occurs.
PATCH 14 isolates the tests that won't fit in the CI
PATCH 15 integrates the CI tests to the test_progs framework

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.
