One other thing: capability. It's not enough to be able to configure
the device, user-space tools also have to know what the device is
capable of before they try touching it. Ie, which ciphers, protocols,
channels, etc. Similar to the IWRANGE ioctl that there is now. Half
the problem now is that you can't reliably tell what drivers support
which features, or how much they support a particular feature. Think of
ethernet devices and whether or not they support carrier detection,
there's absolutely no way to tell that now (unless they respond to
ethtool or MII, and some cards freeze if you touch them with MII too
often).
