This option prevents TCP small segment attack. With this option set, Onload limits the number of packets inside TCP receive queue and TCP reorder buffer. In some cases, this option causes performance penalty. You probably want this option if your application is connecting to untrusted partner or over untrusted network.

Off by default.
