I see something that I think is similar with iperf3 and netperf. Using 1 stream
is fine but using >1 stream completely kills bandwidth.

`iperf3 --sctp -c` is OK. `iperf3 --sctp --nstreams 1 -c`
is not. (Yes with 1 stream)

`netperf -t SCTP_STREAM -H` is OK. `netperf -t SCTP_STREAM_MANY -H -- -T 2` is not.
