That sounds like we could "hack around" it by sending the S1G data first, and then the 2.4 GHz, so the latter overwrites it on broken versions? Not sure it's worth it though, I'd say it depends a bit on what real hardware plans are? I mean, if it's only hwsim for now ... who cares? And if it's going to be special hardware that only does S1G, then also meh, you need newer versions to support it, big deal. But if OTOH a commonly used chipset like e.g. ath9k or ath10k will get S1G support, then that'd be more relevant? johannes
