rdma/rdma_shared_device_a resources allocation

[cairong-ai]

rdmaSharedDevicePlugin:
deploy: true
resources:
- name: rdma_shared_device_a
ifNames: [ibs10, ibs11, ibs18, ibs19]

I have deployed the network-operator using the configuration shown above, and I see that on the node it displays: rdma/rdma_shared_device_a: 63.
I want to know if these 63 resources are evenly distributing the bandwidth of these IB cards.
If a pod only requests 1 rdma/rdma_shared_device_a resource, how much bandwidth can this pod use?

@cairong-ai if you have access to the device. Can you you run a benchmark to test this ?
