Subject: [PATCH v6 08/15] docs: use parser_yaml extension to handle Netlink specs
Instead of manually calling ynl_gen_rst.py, use a Sphinx extension.
This way, no .rst files would be written to the Kernel source
directories.
We are using here a toctree with :glob: property. This way, there
is no need to touch the netlink/specs/index.rst file every time
a new Netlink spec is added/renamed/removed.
