Is there a simple way for a FreeBSD system to cause its peer to use a transmit segment size of, say, 640 bytes -- so that the peer will never try to send a packet larger than that? I'm trying to get around a network packet-size problem. In case it matters, the other end is SunOS 4.1.1 on a sun3, and I've been unable to find a way to limit its packet size directly.
