The creation of wlan0 already comes from userspace, but the PHY has its own MAC. > We really do not want to announce a netdev when registering the wiphy > device and then having to mess with its MAC address via sysfs somehow. > This all needs to be properly reflected over RTNL. > Again, no netdev is announced. There just isn't a way to set the MAC of the wiphy device itself. How about this: What if the driver were to leave the MAC at all zeros initially, and sysfs could set that if and only if it's all zeros at the time? -- 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
