On the receive path, the checksum offload calculates the checksums in the IP, TCP, and UDP headers as appropriate and indicates to the OS whether the checksums passed, failed, or not checked. If the computed checksum fails, the packet gets discarded.

Checksum offloading is also required for other stateless offloads to work including receive side scaling RSS , receive segment coalescing RSC , and large send offload LSO.
