The api is defined in sys/dev/ath/if_athrate.h. 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.
