Many implementations of TCP running over IPv6 neglect to check the IPV6\_USE\_MIN\_MTU value when performing MSS negotiation and when constructing a TCP segment. This leads to oversized IPv6 packets being sent resulting in unintended Path Maximum Transport Unit Discovery (PMTUD) {[}RFC1191{]} being performed and to fragmented IPv6 packets being sent.}, }
