Is it a good idea to add a configuration item for dvr, to disable any arp entry processing, and reuse arp response from L2population?

When no static arp entry is found in qrouter namespace, it would cause a temp arp request, then it reached the br-tun, and replied by the OVS flow table.

In a public cloud like AWS, it allow 200 subnets for each vpc, so sync routes would waste a lot of time
