/* * 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 <mike.mclagan@linux.org> * * 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.
