(1) If you add "Idle -> ToDevice(X)", that shouldn't actually take very much CPU. (2) BUT you are right. I think maybe this message is left over from an older version of Click. Is anyone using polling device drivers? Can anyone confirm whether or not ToDevice helps performance in a sniffer-only PollDevice configuration?
