+ * This file contains the implementation of the Device class.
+ *
+ *		FIXME:
+ * We may need to check how smo-subnet-nbits is used in here because we didn't
+ * actually check to see under what conditions it's required vs optional. Hence
+ * we don't currently enforce correct usage of it, and we just assume that the
+ * livoxGen1's policy of supplying a default value of 24 is correct.
