[PATCH net-next v8 0/5] doc/netlink: Expand nftables specification

[Remy D. Farley]

Getting out some changes I've accumulated while making nftables work
with Rust netlink-bindings. Hopefully, this will be useful upstream.

v8:
- De-duplicate operation attributes.
- Fix typo in max-check, add missing max-check.

v7: https://lore.kernel.org/netdev/20260202093928.742879-1-one-d-wide@protonmail.com/
- Drop "getcompat" operation.
- Fix formatting of lists of attrsets.

v6: https://lore.kernel.org/netdev/20260121184621.198537-1-one-d-wide@protonmail.com/
- Sort sub-messages.
- Add description for "Add max check" commit.
- Fix doc comment for expr-bitwise-attrs to match one in nf_tables.h (thanks Donald)

v5: https://lore.kernel.org/netdev/20251120151754.1111675-1-one-d-wide@protonmail.com/
- Fix docgen warnings in enums (avoid interleaving strings and attrsets in a list).
- Remove "# defined in ..." comments in favor of explicit "header" tag.
- Split into smaller commits.

v4: https://lore.kernel.org/netdev/cover.1763574466.git.one-d-wide@protonmail.com/
- Move changes to netlink-raw.yaml into a separate commit.

v3: https://lore.kernel.org/netdev/20251009203324.1444367-1-one-d-wide@protonmail.com/
- Fill out missing attributes in each operation (removing todo comments from v1).
- Add missing annotations: dump ops, byte-order, checks.
- Add max check to netlink-raw specification (suggested by Donald Hunter).
- Revert changes to ynl_gen_rst.py.

v2: https://lore.kernel.org/netdev/20251003175510.1074239-1-one-d-wide@protonmail.com/
- Handle empty request/reply attributes in ynl_gen_rst.py script.

v1: https://lore.kernel.org/netdev/20251002184950.1033210-1-one-d-wide@protonmail.com/
- Add missing byte order annotations.
- Fill out attributes in some operations.
- Replace non-existent "name" attribute with todo comment.
- Add some missing sub-messages (and associated attributes).
- Add (copy over) documentation for some attributes / enum entries.
- Add "getcompat" operation.
