Ok, this means:

- the ralink rate control algorithm is not part of the firmware /
  hardware and thus cannot be used (directly) by rt2x00.

- rt2x00 probably uses minstrel? Is minstrel able to optimally support
  the needs of ralinks hardware?
  Background: Is the presumption correct, that ralink might possibly
  cover some quirks of there hardware with an aligned algorithm?



Thanks,
