Couldn't we just initialise the softmac txrates substructure to
something useful when associating, and have drivers look into that
instead?

This isn't correct. Here, you have to take into account multicast frames
because those require clamping the rate to the highest rate from the
basic rateset.
I'll try to come up with an alternative.
