[BUG]把一个EIP解邦后再邦定给另外一个VPC 的虚拟机， 会出现ping 这个EIP 时断的情况 。

[khw934]

问题描述/What happened:
把一个EIP解邦后再邦定给另外一个VPC 的虚拟机， 会出现ping 这个EIP 时断的情况 ，通过抓包分析发现解绑或者删除EIP 存在清理不全的情况
环境/Environment:
EIP 网关是独立部署的， 如果EIP 不存在重复使用的情况下， 网络是正常的。

以
21.zip
下是通过抓包分析的情况

这是从 EIP 网关抓的包

只要重新启动 EIP 网关 yunion-sdnagent-eipgw ， 就正常。

我把这个问题复现了
删除 虚拟机的时候， 如不不选择删除EIP ， 后面再创建虚拟机， 选择之前的EIP，就有问题了

这是 在 EIP 网关查询出来的 flows 记录 ， 对应的vpc 地址是错误，

重新启动 systemctl restart yunion-sdnagent-eipgw ，flows 记录 就对了

这有问题？
