Some network interface cards support the Rx Checksum Offload/Tx Checksum Offload option. Generally, the TCP/IP protocol suite on the Windows platform calculates the TCP/UDP/IP checksum. If the Rx Checksum Offload/Tx Checksum Offload option is enabled on the network card, the network card itself rather than the protocol suite calculates the checksum. In this case, the TCP checksum calculated by the network card is different from the one parsed by the packet head getting software.
