It isn't clear you can. An application using UDP is expecting message
boundaries to be preserved. That is a fundamental part of the semantics
of UDP. So if an application has sent three, 128 byte messages via UDP,
the receiving side is expecting to receive three, 128 byte messages, not
one 384 byte message. If the receiver can indeed deal with just one,
384 byte message, that is what the sending side should have sent in the
first place.
