/* EROS device configuration data structure.  After some waffling back
 * and forth, I've decided to adopt the PCI notion of classes and
 * subclasses.  Under this model, all (e.g.) ethernet interfaces will
 * register themselves as CLASS=NETWORK SUBCLASS=Ethernet.  There will
 * be a single 'device creator' key for each class.
 * 
 * Implicit in adopting this design is a change of plan w.r.t. device
 * specific interfaces.
