Kubernetes 集群准备使用 eBPF，参考 Calico 的帮助文档 Enable the eBPF dataplane，在配置Configure Calico to talk directly to the API server 过程中添加 ConfigMap 后

kind: ConfigMap
apiVersion: v1
metadata:
  name: kubernetes-services-endpoint
  namespace: kube-system
data:
  KUBERNETES_SERVICE_HOST: "k8s-api"
  KUBERNETES_SERVICE_PORT: "443"

calico-kube-controllers pod 无法启动，错误信息如下：

Failed to create pod sandbox: rpc error: code = Unknown desc = [failed to set up sandbox container "xxx" network for pod "calico-kube-controllers-56fcbf9d6b-45zpf":

请问如何解决？
