[mptcp-next,0/5] convert MPTCP to use YAML spec

Message

Davide Caratti July 21, 2023, 9:53 a.m. UTC

this series converts most of the MPTCP netlink interface (plus uAPI bits)
to use sources generated by a YAML spec file. Patch 2/5 and 5/5 have been
individually verified with kselftests.

POC:

 $ sudo  ./tools/net/ynl/cli.py  --spec \
 > Documentation/netlink/specs/mptcp.yaml --do add_addr \
 > --json '{"addr": {"addr4": 16909061, "family": 2, "flags": 4, "id": 10, "port": 0}}'

 $ ip -j mptcp endpoint show  id 10
 [{"address":"1.2.3.5","id":10,"backup":true}]
