+ *  UWB radio controller:

+ *    1. alloc a uwb_rc, zero it
+ *    2. call uwb_rc_init() on it to set it up + ops (won't do any
+ *       kind of allocation)
+ *    3. register (now it is owned by the UWB stack--deregister before
+ *       freeing/destroying).
+ *    4. It lives on it's own now (UWB stack handles)--when it
+ *       disconnects, call unregister()
+ *    5. free it.
+ *
+ *    Make sure you have a reference to the uwb_rc before calling
+ *    any of the UWB API functions.
+ *
+ * TODO:
+ *
+ * 1. Locking and life cycle management is crappy still. All entry
+ *    points to the UWB HCD API assume you have a reference on the
+ *    uwb_rc structure and that it won't go away. They mutex lock it
+ *    before doing anything.
