Issues running flent / packaging into container

[xciter327]

I wanted to run some test on Fedora 34, which seems to have lost the netperf package. So I decided to give packaging Flent into a container a go. I'm having some issues actually running the thing. Output from tring to run it:

➜  flent git:(master) ✗ podman run -it --network=host 0c4ea2cce3e flent rrul -p all_scaled -l 60 -H netperf.bufferbloat.net
Started Flent 2.0.0 using Python 3.9.5.
Traceback (most recent call last):

Python version:

➜  flent git:(master) ✗ podman run -it --network=host 0c4ea2cce3e python3 --version
Python 3.9.5

Relevant dockerfile:

➜  flent git:(master) ✗ cat Dockerfile

    apt-get install -y locales software-properties-common && \

Hmm, my guess would be that this happens because the container doesn't have 'hexdump' available. Really shouldn't cause a crash, though, that's definitely a bug...

And yeah, I really ought to do something about that missing netperf package (you're the second person pointing it out in the last couple of days)...
