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
