Use the libbpf skeleton facility and other utilities provided by XDP samples helper. One important note: The XDP samples helper handles ownership of installed XDP programs on devices, including responding to SIGINT and SIGTERM, so drop the code here and use the helpers we provide going forward for all xdp_redirect* conversions.

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.
