Hi,
My test system is broken.
I was using a kernel build a couple of days ago while I was doing the
initial test with the new rate control function.
Since I was getting deviant result, I decided to build a fresh kernel
before I continue my test. I also had added some debugging to see what
actually happens.
Unfortunately the rt2x00/rt61pci driver is broken in current git. I'm using
http://www.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git,
and the 'everything' branch.
I got plenty of :

I think it has something to do with the "cfg80211 API for channels/bitrates,
mac80211 and driver conversion" commit.
I will get back as soon as my test system is up and running again.
Regards
Lars
