That's very likely due to the ANI changes I've been slowly porting over. I really would like someone who is interested in the radio side of things to pick up the ANI code as a bit of a personal research project. It's one of the areas of the atheros stuff which is actually well covered in the patent literature and I can help interested people out with it. There's a lot of cool stuff you can affect by tweaking the ANI related parameters (which are all just receive-side radio and baseband parameters to do with signal levels and signal trigger thresholds.) It's actually kind of fun. :) Adrian
