G'day,

I've been working away on automation of the tests.  Pretty close to having
much nicer tests with a lot more details.  I've also got the risc-v device
working.

However, I've run into something funny with flent.  Flent is not happy with
fping or ping.

das@3rd:~/Downloads/cake/cmd/run_qdiscs_tests$ /usr/bin/sudo /usr/sbin/ip
netns exec network101 /usr/bin/flent rrul --output

I did install via "apt install fping"

Any thoughts please?

Kind regards,
Dave
