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,
