Right, let me split this patch into two patches and resend the V2.

Right, isn't that a more critical fix to make by itself instead of
rolling into this change that adds a few more frequencies?

rate_count is necessary for table search during set_rate, it was missed 
previously,
I will add it into commit text in V2.

Why is rate_count added? That's not described in the commit text.
