Add a new test where some of the packets are not passed to the AF_XDP socket and instead get a XDP_DROP verdict. This is important as it tests the recycling mechanism of the buffer pool. If a packet is not sent to the AF_XDP socket, the buffer the packet resides in is instead recycled so it can be used again without the round-trip to user space. The test introduces a new XDP program that drops every other packet.

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.
