I can provide you with the source the the 4.3BSD tcp as hacked to run with
the Sun 4.2 IP. It makes a tremendous difference in performance.
It often is the difference between making a connection or not being able to 
connect at all.

Based on the following, I am assuming that you don't even need a source
license. (Right Mike?)

	The Berkeley 4.2/4.3BSD TCP/IP code is written in C.  It's not quite
	public domain (it is copyright by the university), but the only
	restriction on its use is that the University of California be
	credited.
