It's more complicated - since if you're not doing aggregation, the
overheads per frame eat in to your efficiency % and when you're
transmitting at high MCS or multiple streams, you don't necessarily
get a linear increase in throughput.

If aggregation is correctly working, you should see ~ 150MBit/sec TCP
between two 2x2 40MHz nodes, and roughly half/quarter that for
1-stream 20 and 2-stream 20 (or 1 stream 20 versus 1 stream 40.)
