1/* 2 * DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are 3 * created for each DLCI associated with a FRAD. The FRAD driver 4 * is not truly a network device, but the lower level device 5 * handler. This allows other FRAD manufacturers to use the DLCI 6 * code, including its RFC1490 encapsulation alongside the current 7 * implementation for the Sangoma cards. 8 * 9 * Version: @(#)if_ifrad.h 0.15 31 Mar 96 10 * 11 * Author: Mike McLagan <mike.mclagan@linux.org> 12 * 13 * Changes: 14 * 0.15 Mike McLagan changed structure defs (packed) 15 * re-arranged flags 16 * added DLCI_RET vars 17 * 18 * This program is free software; you can redistribute it and/or 19 * modify it under the terms of the GNU General Public License 20 * as published by the Free Software Foundation; either version 21 * 2 of the License, or (at your option) any later version. 22 */ 23 24#ifndef _UAPI_FRAD_H_ 25#define _UAPI_FRAD_H_ 26 27#include <linux/if.h> 28 29/* Structures and constants associated with the DLCI device driver */ 30 31struct dlci_add 32{ 33 char devname[IFNAMSIZ]; 34 short dlci; 35}; 36 37#define DLCI_GET_CONF (SIOCDEVPRIVATE + 2) 38#define DLCI_SET_CONF (SIOCDEVPRIVATE + 3) 39 40/* 41 * These are related to the Sangoma SDLA and should remain in order. 42 * Code within the SDLA module is based on the specifics of this 43 * structure.
