TCP: C2S Ambiguity Mismatching TS Opt in SYN Retrans
This protocol anomaly triggers when it detects a TCP SYN retransmission where the TIMESTAMP option did not match the one that was specified with the original SYN. IDP cannot tell the initial TIMESTAMP, as it is unknown whether the server has received the first SYN.
