Add a "--multi <do-op> <json>" command line to ynl that makes it
possible to add several operations to a single netlink request payload.
The --multi command line option is repeated for each operation.
This is used by the nftables family for transaction batches. For
example:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi batch-begin '{"res-id": 10}' \
--multi newtable '{"name": "test", "nfgen-family": 1}' \
--multi newchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--multi batch-end '{"res-id": 10}'
[None, None, None, None]
It can also be used for bundling get requests:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi gettable '{"name": "test", "nfgen-family": 1}' \
--multi getchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--output-json
[{"name": "test", "use": 1, "handle": 1, "flags": [],
"nfgen-family": 1, "version": 0, "res-id": 2},
{"table": "test", "name": "chain", "handle": 1, "use": 0,
"nfgen-family": 1, "version": 0, "res-id": 2}]
