Abstract:
A network stack sends very large packets with large segment offload (LSO) by performing multi-pass LSO. A first-stage LSO filter is inserted between the network stack and the physical NIC. The first-stage filter splits very large LSO packets into LSO packets that are small enough for the NIC. The NIC then performs a second pass of LSO by splitting these sub-packets into standard MTU-sized networking packets for transmission on the network.
