The openvswitch family has a fixed header, uses struct attrs and has array values. This partial spec demonstrates these features in the YNL CLI. These specs are sufficient to create, delete and dump datapaths and to dump vports: $ ./tools/net/ynl/cli.py \ --spec Documentation/netlink/specs/ovs_datapath.yaml \ --do dp-new --json '{ "dp-ifindex": 0, "name": "demo", "upcall-pid": 0}' None $ ./tools/net/ynl/cli.py \ --spec Documentation/netlink/specs/ovs_datapath.yaml \ --dump dp-get --json '{ "dp-ifindex": 0 }' [{'dp-ifindex': 3, 'masks-cache-size': 256, 'megaflow-stats': {'cache-hits': 0, 'mask-hit': 0, 'masks': 0, 'pad1': 0, 'padding': 0}, 'name': 'test', 'stats': {'flows': 0, 'hit': 0, 'lost': 0, 'missed': 0}, 'user-features': {'dispatch-upcall-per-cpu', 'tc-recirc-sharing', 'unaligned'}}, {'dp-ifindex': 48, 'masks-cache-size': 256, 'megaflow-stats': {'cache-hits': 0, 'mask-hit': 0, 'masks': 0, 'pad1': 0, 'padding': 0}, 'name': 'demo', 'stats': {'flows': 0, 'hit': 0, 'lost': 0, 'missed': 0}, 'user-features': set()}] $ ./tools/net/ynl/cli.py \ --spec Documentation/netlink/specs/ovs_datapath.yaml \ --do dp-del --json '{ "dp-ifindex": 0, "name": "demo"}' None $ ./tools/net/ynl/cli.py \ --spec Documentation/netlink/specs/ovs_vport.yaml \ --dump vport-get --json '{ "dp-ifindex": 3 }' [{'dp-ifindex': 3, 'ifindex': 3, 'name': 'test', 'port-no': 0, 'stats': {'rx-bytes': 0, 'rx-dropped': 0, 'rx-errors': 0, 'rx-packets': 0, 'tx-bytes': 0, 'tx-dropped': 0, 'tx-errors': 0, 'tx-packets': 0}, 'type': 'internal', 'upcall-pid': [0], 'upcall-stats': {'fail': 0, 'success': 0}}] Signed-off-by: Donald Hunter <donald.hunter@gmail.com> --- Documentation/netlink/specs/ovs_datapath.yaml | 153 ++++++++++++++++++ Documentation/netlink/specs/ovs_vport.yaml | 139 ++++++++++++++++ 2 files changed, 292 insertions(+) create mode 100644 Documentation/netlink/specs/ovs_datapath.yaml create mode 100644 Documentation/netlink/specs/ovs_vport.yaml
