Yeah, this looks like it's a matter of the internal test configuration
API having changed...

To do this you could do something like this:

flent tcp_nup --test-parameter upload_streams=7 --test-parameter markings=11,13,15,17,19,10,1

However, this currently only works with tcp_nup and tcp_ndown; there's
currently no support in any of the RRUL tests. I can add an rrul_var
test where you can specify number of streams, and parameters such as
markings for each one (matching them so there will be one stream in each
direction + a UDP measurement stream for each setting). Would that work
for your use case, do you think?
