AP performance (again): txpower regulation

[Adrian Chadd]

Look at all of those OFDM errors. That's a big, big part of your problem.

It's possible that there's some problem with the driver code and it's
somehow setting up the RX side of your NIC incorrectly, causing lots
of those OFDM errors.
But it's also very likely you've just got a lot of noise in your local
environment.

You could try disabling ANI (sysctl dev.ath.0.intmit=0) and see if
things behave better/worse. You won't get OFDM/CCK error counts
though, so don't assume "0" for those counts magically means they went
away.

I haven't yet tidied up and committed tools which let you tweak the
ANI settings manually. This may be of some help/interest to you.

Finally, if you/someone sends me one of those NICs, I can try using it
here and see how it behaves. :)
