Under load, otherwise stable rates can easily fluctuate because of collisions. In my tests on a clean channel, the success probability of the max throughput rate often stays somewhere between 90% and 100% under load. This can cause some unnecessary switching to lower rates. This patch improves stability by treating success probability values between 90% and 100% the same. In my tests on a 3x3 HT20 link with lots of TCP traffic, it improves the average throughput by a few mbit/s. Signed-off-by:
