Implement automatic switching of XDP programs and execution modes if needed by a test. This makes it much simpler to write a test as it only has to say what XDP program it needs if it is not the default one. This also makes it possible to remove the initial explicit attachment of the XDP program as well as the explicit mode switch in the code. These are now handled by the same code that just checks if a switch is necessary, so no special cases are needed. The default XDP program for all tests is one that sends all packets to the AF_XDP socket. If you need another one, please use the new function test_spec_set_xdp_prog() to specify what XDP programs and maps to use for this test.

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.
