Hi,

I don't know that making a loopback is a good idea.  There is a fair chance you'll let 
the smoke out of the interface chips.  This makes them unusable.  I also don't know 
how you would address such a thing.

Most IP stacks can be tested by pinging yourself.  There are various bits of software 
around that do testing of NIC's.  There are a number of packages that inject traffic 
onto networks that will allow testing.

If you really want to send something up itself you could try making a cable that 
connects pin 1 - 3 and pin 2 - 6.  What it will do is not necessarily what you need.  
But, don't let the smoke out of the interface chips.
