No it is not. It is fixing the issue. It fixes the following issues:
* You must ignore the Txstat-requested bit in the driver.
* You must report bad frames with the excessive_retries set.

The issue you are (most likely) talking about is that we can not
reliably tell whether a frame was good in the driver. That is a different
issue completely seperate from the two points above, which my patch fixes.

With my patch rate-controlling correctly works. Without it does not.

If you find a way to fix the reliable-detection-of-good-TX issue, that's
another good fix. But I think it's not release critical, because the
device works with the current "guessing-around" code. But without the two
points above fixed, it does not correctly work at all (unless you manually
tune to the best rate each time you move the machine).
