When the poll value in a client request is smaller than the server's NTP rate limiting interval, set poll in the response to the rate limiting interval to suggest the client to increase its polling interval. This follows ntpd as a server. No current client implementation seems to be increasing its interval by the poll, but it may change in the future.
