multus网卡配置不生效

[tiezhuoyu]

Expected Behavior

使用multus配置网卡attachnet1，并指定attachnet1的子网为net1

Actual Behavior

配置不生效，attachnet1网卡最后分配到默认子网

Steps to Reproduce the Problem

1. 创建测试pod
   cat centos-tools-pod.yaml
   apiVersion: v1
   kind: Pod
   metadata:
   name: centos-tools
   annotations:
   v1.multus-cni.io/default-network: default/attachnet1
   attachnet1.default.ovn.kubernetes.io/logical_switch: net1
   spec:
   containers:
   - name: centos
   image: centos/tools
   command:
   - /sbin/init
   ports:
   - containerPort: 80

kubectl apply -f centos-tools-pod.yaml

2. 查看pod ip处于默认子网10.16.0.0/16，而不是指定子网net1
   kubectl get po -owide centos-tools

pod ip 显示的是主网卡 ip，需要进到容器里去看附属网卡ip

[tiezhuoyu]

只有这一张网卡的，我通过“v1.multus-cni.io/default-network: default/attachnet1”这个配置设置默认网卡

@tiezhuoyu 能不能把 attach-network 和 subnet 等 yaml 发一下，我们复现一下
