Currently, a devlink rate's parent device is assumed to be the same as
the one where the devlink rate is created.
This patch changes that to allow rate commands to accept an additional
argument that specifies the parent dev. This will allow devlink rate
groups with leafs from other devices.
Example of the new usage with ynl:
Creating a group on pci/0000:08:00.1 with a parent to an already
existing pci/0000:08:00.1/group1:
./tools/net/ynl/pyynl/cli.py --spec \
Documentation/netlink/specs/devlink.yaml --do rate-new --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.1",
"rate-node-name": "group2",
"rate-parent-node-name": "group1",
"parent-dev": {
"bus-name": "pci",
"dev-name": "0000:08:00.1"
}
}'
Setting the parent of leaf node pci/0000:08:00.1/65537 to
pci/0000:08:00.0/group1:
./tools/net/ynl/pyynl/cli.py --spec \
Documentation/netlink/specs/devlink.yaml --do rate-set --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.1",
"port-index": 65537,
"parent-dev": {
"bus-name": "pci",
"dev-name": "0000:08:00.0"
},
"rate-parent-node-name": "group1"
}'
