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.
