So I want to get back to this as to assure we have the same
understanding. First off, the proposed offloads are STA-only. So if a
driver supports STA and AP mode and the 4-way-HS offload, we could
already have the case you describe here. So not really a "bolted on"
scenario I would say. It does raise the question whether or not we want
similar offloads for AP.
