Hi,

while I think this functionality is of use, I don't think it should go
into testpmd. Testpmd is designed for testing NIC PMDs, and not as a
general test tool, and is already complicated enough with lots of
commandline options. For the task of testing VNF use-cases, I think a
new separate app or example would be better.

My 2c.
