TCP: C2S Ambiguity Mismatching WSF Opt in SYN Retrans

This protocol anomaly triggers when it detects a TCP SYN retransmission where the window scaling factor does not match the one that was specified with the original SYN. Because it is unknown if the server received the first SYN, IDP cannot determine the window size.
