   3  * DLCI/FRAD    Definitions for Frame Relay Access Devices.  DLCI devices are
   4  *              created for each DLCI associated with a FRAD.  The FRAD driver
   5  *              is not truly a network device, but the lower level device
   6  *              handler.  This allows other FRAD manufacturers to use the DLCI
   7  *              code, including its RFC1490 encapsulation alongside the current
   8  *              implementation for the Sangoma cards.

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