Need help with configuring large packet size on Solaris 7 / e6500

Greetings, I'm stuck in a time warp using ancient machines from the prehistoric era that should be rightfully displayed in the Smithsonian. We're running Solaris 7 on FDDI n/w on an E6500 host and wish to use MTU (packet size) > 1500, more like 3072 bytes to begin with and possibly up to 4096...

NAME

       spray - spray packets

SYNOPSIS

       /usr/sbin/spray [-c count] [-d delay] [-l length]
	    [-t nettype] host

DESCRIPTION

       spray sends a one-way stream of packets to host using RPC, and reports how many were received, as well as the transfer rate. The host argu-
       ment can be either a name or an Internet address.

       spray is not useful as a networking benchmark, as it uses unreliable connectionless transports, UDP for example. spray can report  a  large
       number of packets dropped when the drops were caused by spray sending packets faster than they can be buffered locally, that is, before the
       packets get to the network medium.

OPTIONS

       -c count      Specify how many packets to send. The default value of count is the number of packets required to make the total stream  size
		     100000 bytes.

       -d delay      Specify how many microseconds to pause between sending each packet. The default is 0.

       -l length     The  length  parameter  is  the  numbers  of  bytes in the Ethernet packet that holds the RPC call message. Since the data is
		     encoded using XDR, and XDR only deals with 32 bit quantities, not all values of length are possible, and spray rounds  up	to
		     the nearest possible value. When length is greater than 1514, then the RPC call can no longer be encapsulated in one Ethernet
		     packet, so the length field no longer has a simple correspondence to Ethernet packet size. The default value of length is	86
		     bytes, the size of the RPC and UDP headers.

       -t nettype    Specify class of transports. Defaults to  netpath. See rpc(3NSL) for a description of supported classes.
