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
