+ * Revision 1.12 2000/01/28 16:45:39 calle
+ * new manufacturer command KCAPI_CMD_ADDCARD (generic addcard),
+ * will search named driver and call the add_card function if one exist.
+ *
+ * Revision 1.11 1999/11/23 13:29:29 calle
+ * Bugfix: incoming capi message were never traced.
+ *
* Revision 1.10 1999/10/26 15:30:32 calle
* Generate error message if user want to add card, but driver module is
* not loaded.
