Yes, something seems to be wrong.
Using just 1 stream with iperf, the average A-MPDU length never
goes above 10 and the throughput is about 90 Mbps.
Using 4 iperf streams (using -P), the average A-MPDU length goes up to 22
and throughput reaches about 102 Mbps.
This is with HT20. Using HT40 shows the behavior for 1 iperf stream.
