[bpf-next,v2,0/2] Add table of BPF program types to docs

Message

Extend the libbpf documentation with a table of program types, attach
points and ELF section names. The table uses data from program_types.csv
which is generated from tools/lib/bpf/libbpf.c during the documentation
build.

Patch 1 adds subdir support to Documentation/Makefile and changes
userspace-api/media to use this instead of being a special case.

Patch 2 adds the the program_types documentation with a new makefile in
the libbpf doc directory to generate program_types.csv

I plan to look at adding info about format of section "extras" as a
follow-on.

v1 -> v2:
Automate the generation of program_types.csv as suggested by
Andrii Nakryiko.
