Large Send Offload

This networking enhancement is new in the Developer 2/07 release.

Large Send Offload (LSO) is a hardware off-loading technology. LSO off-loads TCP Segmentation to NIC hardware to improve the network performance by reducing the workload on the CPUs. LSO is helpful for 10Gb network adoption on systems with slow CPU threads or lack of CPU resource. This feature integrates basic LSO framework in Solaris TCP/IP stack, so that any LSO-capable NIC might be enabled with LSO capability.
