Description:
	Chris, is your fix here really necessary?  For testing
	ethernet interfaces (the reason you claimed for your mod),
	I think it would be more conclusive to run Mike Muess's
	ICMP echo sender and bounce packets off of another host.
	If this test fails it's time to swap the xcvr/board or
	run a more exhaustive diagnostic.  Using your test
	method (machine talking to itself on the ether)
	would still be an intermediate step before running
	the ICMP test, since I can imagine certain ether
	failure modes (weak transmitter) that would pass
	your test but fail the ICMP echo.

Repeat-By:
	NA

Fix:
	Unnecessary?
