What happened?

Once you use annotation "ipam.spidernet.io/ippools" to specify IPPools for multiple NICs, you can use the "cleangateway" property to specify whether this NIC allocation need default route with the IPPool's gateway.

But this field just works for the first NIC and it does not works for the second or latter NIC. For example, this following annotation not works

ipam.spidernet.io/ippools: |-
  [{
      "interface": "eth0",
      "ipv4": ["demo-v4-ippool1"],
      "ipv6": ["demo-v6-ippool1"],
      "cleangateway": false
   },{
      "interface": "net1",
      "ipv4": ["demo-v4-ippool2"],
      "ipv6": ["demo-v6-ippool2"],
      "cleangateway": true
  }]

What did you expect to happen?

cleangateway property works well
