Next - we need to update the rate control API to now populate an rc array rather than just returning the rix. This is the tricky part - as we're going to have to modify all the drivers that use the rate control API to use this. Which is fine, as there's only a handful. It's just annoying. Then we have to provide the rate control information during frame _completion_, so the rate control code knows which transmission rates succeeded or failed. I'm still not sure what to do about it here. Maybe do something like Linux and attach TX rate control and completion information as an mbuf tag? _Then_ we can start doing interesting thing with it. :) -adrian
