/* * DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are * created for each DLCI associated with a FRAD. The FRAD driver * is not truly a network device, but the lower level device * handler. This allows other FRAD manufacturers to use the DLCI * code, including its RFC1490 encapsulation alongside the current * implementation for the Sangoma cards. * * Version: @(#)if_ifrad.h 0.15 31 Mar 96 * * Author: Mike McLagan <> * * Changes: * 0.15 Mike McLagan changed structure defs (packed) * re-arranged flags * added DLCI_RET vars * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * as published by the Free Software Foundation; either version * 2 of the License, or (at your option) any later version. */ #ifndef _FRAD_H_ #define _FRAD_H_ #include <linux/config.h> #include <linux/if.h> #if defined(CONFIG_DLCI) || defined(CONFIG_DLCI_MODULE) /* Structures and constants associated with the DLCI device driver */ struct dlci_add { char devname[IFNAMSIZ]; short dlci; }; #define DLCI_GET_CONF (SIOCDEVPRIVATE + 2) #define DLCI_SET_CONF (SIOCDEVPRIVATE + 3) /* * These are related to the Sangoma SDLA and should remain in order. * Code within the SDLA module is based on the specifics of this * structure.
