I still don't see what stops you from doing this in userspace, I don't remember a compelling reason for implementing this in the kernel. Clearly, you need to modify userspace anyhow. Also, what if, in the future, we have multiplel STA interfaces on different channels? Which one(s) should it pick then? The -1 trick will also break all non-mac80211 drivers, or maybe simply not work? 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
