Well if you're on an ethernet network, the mtu (max transmission unit i
believe) can be at most 1500, so you shouldn't be able to send packets
larger then that anyway.

I have a very similar system as yours (my uname -a lists the following)
SunOS scooby 5.4 generic sun4c sparc
(the only difference being the name and 4m/4c)
And the only way I know of to set the packet size is the following:
ifconfig le0 (or whatever your enet interface is..) mtu 1500 (or whatever
you want the ethernet mtu to be, max is 1500).
Hope this helps.
