Why does sriov-cni not support assigning multiple VFS to Pods

[ferris-cx]

When a pod applies for 2 VF, only one net network interface can be seen inside the pod, and 2 are expected. What is the reason? Is there a limit to the sriov-cni version? Is it only supported by a higher version?
1、pod.yaml如下：
apiVersion: v1
kind: Pod
metadata:
name: pod-vf2
annotations:
k8s.v1.cni.cncf.io/networks: sriov-attach-ens11f1np1
spec:
containers:

• name: container-vf2
  image: centos/tools
  command: [ "/bin/bash", "-c", "--" ]
  args: [ "while true; do sleep 300000; done;" ]
  resources:
  requests:
  cpu: 1
  memory: 1Gi
  koordinator.sh/rdma: '2'
  limits:
  cpu: 1
  memory: 1Gi
  koordinator.sh/rdma: '2'

2、NAD定义如下：
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: sriov-attach-ens11f1np1
namespace: default
annotations:
k8s.v1.cni.cncf.io/resourceName: mellanox.com/rdma
spec:
config: '{
"cniVersion": "0.3.1",
"name": "sriov-attach",
"type": "sriov",
"capabilities": {
"mac": true,
"ipam": true
},
"master": "ens11f1np1",
"mode": "bridge",
"ipam": {
"type": "host-local",
"subnet": "10.10.10.0/24"
}
}'
3、RDMA NIC name of node1：ens11f1np1

In this scenario, you need to declare two network interfaces, for example:
[这种场景下，你需要声明两个网络接口，例如]：
metadata:
name: pod-vf2
annotations:
k8s.v1.cni.cncf.io/networks: sriov-attach-ens11f1np1@ens11f1np0,k8s.v1.cni.cncf.io/networks: sriov-attach-ens11f1np1@ens11f1np1
In addition, the two VFs assigned to the Pod need to come from two PFs; after all, the same physical NIC device cannot be used twice for the same Pod
[另外，分配给Pod的两个VF需要来自于两个PF，毕竟同一个物理NIC设备不能给同一个Pod用两次]

Thanks @xxsoul that is the right answer!

@ferris-cx let me know if I can close this issue.
