TCP Segmentation Offload (TSO) enables the adapter cards to accept a large amount of data with a size greater than the MTU size. The TSO engine splits the data into separate packets and inserts the user-specified L2/L3/L4 headers automatically per packet. With the usage of TSO, CPU is offloaded from dealing with a large throughput of data.
