There is a loopback sample test (testsuites/samples/loopback in CVS).
Did you use it as an example?  If it is not right, it needs to be fixed.

FWIW the loopback test's primary purpose is to verify that you can at
least link some network application and start the stack on any CPU.  The 
loopback driver is the only one guaranteed to be there across the entire
set of RTEMS BSPs/CPUs.
