   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  *
