This changes the section name for the bpf program embedded in these files to "xdp.frags" to allow the programs to be loaded on drivers that are using an MTU greater than PAGE_SIZE. Rather than directly accessing the buffers, the packet data is now accessed via xdp helper functions to provide an example for those who may need to write more complex programs. v2: remove new unnecessary variable Signed-off-by: Andy Gospodarek <gospo@broadcom.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Acked-by: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://lore.kernel.org/r/20220621175402.35327-1-gospo@broadcom.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
