Ok, could you list what exactly you think is missed?
If we are talking about extra stats, then I still think it is probably easier to add it into l3fwd,
then pull whole l3fwd code into test-pmd.

Hmm, not sure how these 2 things are linked...
Why let say adding fib-fwd into test-pmd will help to decrease l3fwd code complexity?
