采用tigera-operator部署calico，无法指定网卡

参考好文：calico-node报错Readiness probe failed: calico/node is not ready: BIRD is not ready: Error querying BIRD: unable to connect to BIRDv4 socket - Wghdr's Blog!

calico支持这5种修改类型

如果使用kubelet set env修改或kubelet edit修改无法生效，那是因为tigera-operator限制了

要先在daemonset里添加unsupported.operator.tigera.io/ignore: "true"，再执行修改，修改成功后再去掉这条unsupported.operator.tigera.io/ignore: "true"。
