I think for 11n, like ath9k, it might be good enough for 8, but for 11ac could
aggregate a little more.
Yes, and CPU usage goes up after 6 or 7, might due to it generates extra
packets but the physical bus is capping the throughput, so that we can't see
much throughput difference after (or maybe my setup is not optimal, assumed we
should be seeing around 550-600Mbps for TCP in 11ac), but only the CPU usage
