Thanks. This is not an improvement here.

Sitting at my desk, about 5m from my WNDR3800 access point with walls
and chimney in between them, I was previously seeing a TX rate of 48Mb/s
up to 54Mb/s (reported by 'iwconfig wlan0' and also as the RX rate for
the corresponding wireless client in OpenWRT's status page).

A primitive test copying a 143MiB file to a wired host would take 35
seconds, averaging 4.1MiB/s.

With these changes I get TX rates of about 18-24Mb/s and copying the
same file takes 82 seconds, averaging 1.7MiB/s

That's comparing the Fedora 3.8.2-206.fc18.x86_64 kernel with current
wireless-testing, rather than wireless-testing from before and after
your changes. But that shouldn't matter, presumably?

Do you want me to do some more specific tests?
