Is this a good fit to add to the testpmd application? If so, any pointers on where I should add the functionality? It seems like it has latency measurements already, but in the reverse scenario (where it is the DUT).

I think a new forwarding engine can be added for it, please check "struct 
fwd_engine".
Packet payload can contain metada for required calculations.
