Right, i think this might become more common. So may we need to change minstrel_ht as well? > The end result, as far as I can tell, > is you would just have to tell mac80211 to allow > VHT on 2.4Ghz, and revert this patch that Kalle is proposing. Ideally as this is vendor specific it makes sense to implement this at Driver/FW level rather than implementing it at a common stack like mac80211. > Maybe someone that actually knows about these IEs can explain why > they are worth using? These IE's can be parsed in the driver without any mac80211 involvement. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
