If the TCP CRC is incorrect, wouldn't the TOE discard it, NAK the package and get a retransmit ?

I have a situation like this: CPU | | <---------------->port<---------->TCP offload engine <------------->Logic<----------------->Application processing The logic is going to assemble PDUs and pass them on to the application. If a PDU that came in has CRC errors, will the application need to signal the initiator to terminate the session? Say a PDU header from the TCP offload engine was corrupted, how would the "logic" need to handle the data that comes later. How do I ensure that the application receives packets in order? How can I ensure that in such an event the PDU processing logic does not go out of sync? Regards Preetam
