      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 (at) linux.org>
     12  *
     13  * Changes:
     14  *		0.15	Mike McLagan	changed structure defs (packed)
     15  *					re-arranged flags
     16  *					added DLCI_RET vars
