+ *   devno - Identifies the device number.  This must be a number between

+ *     zero CONFIG_CS89x0_NINTERFACES and the same devno must not be

+ *     initialized twice.  The associated network device will be referred

+ *     to with the name "eth" followed by this number (eth0, eth1, etc).

+ *

+ * Returned Value:

+ *   OK on success; Negated errno on failure.

+ *

+ * Assumptions:
