Hello,
I'd like to be able to add latency and packet-out-of-order measurements to testpmd. The idea is that testpmd sends traffic and receives the same traffic after passing through some device/cloud. 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).
e.g.
| testpmd | <==============> | DUT |
Thanks in advance,
Gabe

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