Re: ath9k rate control - busted

So I tested the AP with 11n-only option setting both on 20mhz and 40
mhz channel bandwidth setting (although in reality I only see it
setting itself to 20 mhz). The rates are not so bad, I consistant
usage of MCS4 with throughput sometimes hitting 30mbps on the end
iperf server.

Here is the rcstat

very 2.0s: cat rcstat

So it seems the issues I saw are only caused on extremely noisy environments.
