Oracle Solaris Tunable Parameters Reference Manual

ip_multidata_outbound (Solaris 10 Release)

This parameter was enhanced in the Solaris 10 release to deliver IP fragments in batches to the network driver. For more information, see ip_multidata_outbound.

Description

Enables the network stack to send more than one packet at one time to the network device driver during transmission.
