I agree that test-pmd iofwd is a good reference to track regressions
or analyze performance issues, but I'm not sure it's a real use-case.
To me, it's more important to ensure that l3fwd performance stay stable
compared to iofwd.

I think l3fwd is the most representative of a DPDK application.

Other use-case could include:
- virtualization, maybe using ovdk?
- ip fragmentation / reassembly
- an application that encapsulate or decapsulate in a tunnel
