Merge branch 'mptcp-convert-netlink-code-to-use-yaml-spec'

Mat Martineau says: ==================== mptcp: convert Netlink code to use YAML spec This series from Davide converts most of the MPTCP Netlink interface (plus uAPI bits) to use sources generated by YNL using a YAML spec file. This new YAML file is useful to validate the API and to generate a good documentation page. Patch 1 modifies YNL spec to support "uns-admin-perm" for genetlink legacy. Patch 2 adds support for validating exact length of netlink attrs. Patch 3 converts Netlink structures from small_ops to ops to prepare the switch to YAML. Patch 4 adds the Netlink YAML spec for MPTCP. Patch 5 adds and uses a new header file generated from the new YAML spec. Patch 6 renames some handlers to match the ones generated from the YAML spec. Patch 7 adds and uses Netlink policies automatically generated from the YAML spec. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
