Bill, I wrote a program called "ipsend" some time ago that I later split up
into iptest/ipsend/ipresend.  iptest basically does lots of nasty things,
including attempting to send huge packets, etc.  It does it using NIT/BPF
and DLPI - but I've only tested on Solaris/BSD/Linux.

If you want to have a look at it:

ftp://coombs.anu.edu.au/pub/net/misc/ipsend.tar.gz

To give you a brief of the other programs:
* ipresend takes a tcpdump binary dump/snoop binary dump
or other input (such as textual descriptions of IP packets) and sends that
out through the above;
* ipsend is a command line interface for sending a single packet or doing
  "stealth scanning";

Ideally, ipresend could be used with a know set of inputs which create a
set of nasty packets (that aren't covered in iptest) and you could use that
to test the rigidity of your IP stack after making any changes.  iptest is
a quick and fixed implementation of a fixed number of tests.
