Ovs-agent can process the ports in large sets, then all of these ports will have to update DB status or attributes. But neutron server is centralized. It may have to do something else, or the database processing can be also time-consuming. Because of these, it sometimes returns the RPC timeout exception to ovs-agent. And a fullsync will be triggered in next rpc loop. The restart time is becoming longer and longer. Adds a default step to update the port to reduce the probability of RPC timeout.
