This RFC patch propose enhancements to testpmd to simulate
more realistic behavior of a guest machine engaged in receiving
and sending packets performing Virtual Network Function (VNF).

The goal is to enable simple of measuring performance impact on cache and
memory footprint utilization from various VNF co-located on the
same host machine.

This series of patches adds the new command line switches to
testpmd:

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.
