Since this api is internal to the ath driver I've not done a manual page. As to the difference between the modules, ath_rate_onoe is the algorithm that's been used forever. ath_rate_amrr is an alternative algorithm that is purported to be better. It so happens that Josh Bicket has just come out with a new rate control algorithm that looks to be an improvement over both and as soon as we resolve some issues I intend to commit it to -current for folks to try instead of the onoe algorithm. If it pans out we'll make it the default. Sam
