It seems it would be needed all the way to userspace so it knows whether it can expect multi-vif CSA to be available? Or would you just want to try & fail? Wouldn't that potentially impact channel selection since you'd want to not pick radar channels for multi-vif? Not really sure ... Maybe the expectation is that internally there will be no drivers that don't support it, i.e. if a driver implements the cfg80211 API at all then it must support multi-vif CSA? johannes -- 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
