Ahh, did you mean that should be taken care of by the rate control algorithm?

I agree, if the rate control algortihm returns a rate via txrc.reported_rate
we should just use that without further validation.

Nevertheless, if the rate control algortihm doesn't fill in txrc.reported_rate
we should only account data frames.

Will send an updated patch.
