Tone down the log levels (Log{ERROR,WARN} -> LogCCP)
when we've simply missed a packet. When our Predictor1 CRC is wrong (implying we've dropped a packet), don't send a ResetReq(). Instead, send another CCP ConfigReq(). *shrug* My tests show this as being far worse than the ResetReq as we may have further Nak/Rejs etc and we're basically resetting both our incoming and outgoing compression dictionaries, but rfc1978 says the ConfigReq is correct, so we'd better go along...
