It might be useful to add the above sample testpmd command lines to section 4.12 of the doc/guides/testpmd_app_ug/testpmd_funcs.rst file

> This also replace the proposal done by Mohammad Abdul Awal [1] which
> handles in a more complex way for the same work.

> Note this API has already a modification planned for 18.11 [2] thus those series
