Rafał Miłecki 77c32f0eb6 nl80211: fix code calculating average signal and rate
Using average of previous average and the next value is highly
imprecise. E.g. for values 20, 20, 20, 180 it would result in /average/
of 100 (instead of 60). Fix it by storing & using an info of how many
samples were used for the previous calculation.
