more useful than what? With what are you comparing? And why compare when you're superseding?

I see we're redefining a function here, but is there a smart way to pass a pointer rather than copying the supported rates?
All of the params are pointers, so shouldn't this function be a 'get'? I don't know what the convention is here.
Any other wifi peeps opine here?
