Something like that...I have not looked in detail.  It would
require a re-compile of the firmware at least.

I just don't like that we are depending on the firmware for something
something as tricky as rate control, especially when it seems buggy.

But, I don't have time to deal with trying to move it into
the driver now, and certainly not as a patch I would have to
carry forever in my own tree.

Thanks,
