bpf, doc: add basic README.rst file A README.rst file in a directory have special meaning for sites like github, which auto renders the contents. Plus search engines like Google also index these README.rst files. Auto rendering allow us to use links, for (re)directing eBPF users to other places where docs live. The end-goal would be to direct users towards https://www.kernel.org/doc/html/latest but we haven't written the full docs yet, so we start out small and take this incrementally. This directory itself contains some useful docs, which can be linked to from the README.rst file (verified this works for github).

docs: bpf: Capitalise document heading The majority of files in the kernel documentation index use capitalisation for all words, especially the shorter ones. BPF docs better fit in with the rest of the documentation if the heading is all capitalised. Capitalise document heading. Signed-off-by: Tobin C.

This directory contains documentation for the BPF (Berkeley Packet
Filter) facility, with a focus on the extended BPF version (eBPF).

The Cilium project also maintains a `BPF and XDP Reference Guide`_
that goes into great technical depth about the BPF Architecture.

bpf, docs: Fix ordering of bpf documentation This commit fixes the display of the BPF documentation in the sidebar when rendered as HTML. Before this patch, the sidebar would render as follows for some sections: | BPF Documentation |- BPF Type Format (BTF) |- BPF Type Format (BTF) This was due to creating a heading in index.rst followed by a sphinx toctree, where the file referenced carries the same title as the section heading. To fix this I applied a pattern that has been established in other subfolders of Documentation: 1. Re-wrote index.rst to have a single toctree 2. Split the sections out in to their own files Additionally maps.rst and programs.rst make use of a glob pattern to include map_* or prog_* rst files in their toctree, meaning future map or program type documentation will be automatically included.
