[Nfd-dev] NDN traffic generator

[Junxiao Shi]

Hi Naren

Please attach your configuration files and the exact command line you use
to invoke traffic generator, so that others can try to reproduce the
problem.
Please also mention the version (obtained by `git log | head -1`) of
traffic generator, and the output of `nfd-status`.

Yours, Junxiao
