[PATCH net-next 00/12] tools: ynl-gen: additional C types and classic netlink handling

[Jakub Kicinski <kuba@kernel.org>]

This series is a bit of a random grab bag adding things we need
to generate code for rt-link.

First two patches are pretty random code cleanups.

Patch 3 adds default values if the spec is missing them.

Patch 4 adds support for setting Netlink request flags
(NLM_F_CREATE, NLM_F_REPLACE etc.). Classic netlink uses those
quite a bit.

Patches 5 and 6 extend the notification handling for variations
used in classic netlink. Patch 6 adds support for when notification
ID is the same as the ID of the response message to GET.

Next 4 patches add support for handling a couple of complex types.
These are supported by the schema and Python but C code gen wasn't
there.

Patch 11 is a bit of a hack, it skips code related to kernel
policy generation, since we don't need it for classic netlink.

Patch 12 adds support for having different fixed headers per op.
Something we could avoid in previous rtnetlink specs but some
specs do mix.
