I met a problem these days.
I read the source code about madwifi rate control, and found that the rate adaptation algorithms (e.g. SampleRate, MInstrel) all convert ath_node to sample_node or minstrel_node at first. I looked into the definition of ath_node and other else, but found that the data area are not matched.
So, I am wondering how the conversion processed? Any help will be appreciate.
