In the patch I just submitted, I added TX retry info to the driver for RTL8187L devices. One of the testers of the patch reports that the rate is being adjusted, but that the rate is overestimated and he has to limit it to 11M. His minstrel statistics and his comments are as follows: > rate throughput ewma prob this prob this succ/attempt success > attempts > 1 0.2 29.8 12.5 1( 8) 51 > 86 > 2 0.4 22.6 14.2 0( 0) 6 > 25 > P 5.5 2.7 54.2 100.0 0( 0) 41 > 109 > 11 1.9 20.5 12.5 0( 0) 6 > 30 > 6 2.1 38.4 20.0 0( 0) 7 > 24 > 9 2.0 24.8 8.3 0( 0) 6 > 25 > 12 2.4 21.9 12.5 0( 0) 6 > 52 > 18 3.2 19.9 12.5 0( 0) 6 > 44 > 24 4.7 22.2 12.5 0( 0) 15 > 109 > 36 4.4 14.5 9.0 0( 0) 495 > 2036 > t 48 5.2 13.4 12.5 0( 0) 209 > 1220 > T 54 8.6 19.8 14.2 1( 7) 556 > 4514 > > But It still is a little to optimistic.

The losses for all rates seem to be a little high, and I plan to see if he can change channels, but I would like an expert's analysis of these data.
