Instead of trying to stuff everything into the mode bitfield it turns out it's just easier, clearer, and simpler to use different values for each of the following: 1) the device's supported access technologies and allowed modes 2) the device's current access technology 3) the device's allowed mode preference Since none of the AccessTechnology or AllowedMode stuff has hit a release yet, let's make sure we're doing it the right way early on.
