Subject: [RFC PATCH net-next v4 2/6] devlink: Extend devlink-rate api with queues and new parameters
Currently devlink-rate only have two types of objects: nodes and leafs.
There is a need to extend this interface to account for a third type of
scheduling elements - queues. In our use case customer is sending
different types of traffic on each queue, which requires an ability to
assign rate parameters to individual queues.
Also, besides two basic parameters provided currently: tx_share and tx_max
we also need two additional parameters to utilize the WFQ (Weighted Fair
Queueing) algorithm.
tx_priority - priority among siblings (0-7)
tx_weight - weights for the WFQ algorithm (1-200)
The whole lifecycle of the queue is being managed from the driver.
User using the 'devlink' utility might reconfigure the queue parent to a
different node, or change it's parameters.
Example:
devlink port function rate set pci/0000:4b:00.0/queue/91 parent node_custom
Rename the current 'leaf' node to 'vport', since the old name doesn't make
any sense anymore. And the only use case for the leaf nodes so far seem to
be a 'vport' or 'VF'.
Allow creation of the node elements from the driver. This is needed,
since in our use case it makes sense that the driver first exports it's
initial TX topology.
Rearrange elements in devlink_rate struct to remove holes.
