No executeable by that name. :(

% which traffic-gen
traffic-gen not found


Searching the local package index gives nothing. (Neither does the 
Debian+Ubuntu package indexes)

$ apt-cache search traffic-gen
<empty output>

https://packages.debian.org/index
https://packages.ubuntu.com/


Tried on Pypi to find something by that name.

1. https://pypi.org/search/?q=trafficgen
2. https://pypi.org/search/?q=traffic-gen

The second one gives so many results. It impossible for me to pick out 
where to start looking. 🤯


The commits adding tests/bursts.conf and flent/tests/bursts_11e.conf 
gives me little information to go by concerning the traffic-gen binary.

     Exercise all for 802.11e queues with bursts_11e.conf

     I note that given the structure of the test, we could get away
     from using ping and use netperf throughout.

     Add 'bursts' test configuration for measuring latency under 
intermittent bursts.
