I don't understand how this is sufficient?

Previously, for HE rates, we had configurations for:
 * HE guard interval

I guess I can sort of follow that uplink traffic is a bit different and
not already configured by the setting for rate control we have today,
but why does it not need all these parameters?

Also, why is this not a per-station parameter? OK, maybe we don't really
want it to be a per-station parameter, or maybe the firmware/algorithm
that's selecting things there can't deal with that, but it feels odd to
combine it with the "rate control fixed rate" parameters you have here,
and do that without even any explanation of how this is supposed to

This is going to need some work.
