+ * DLCI/FRAD   Definitions for Frame Relay Access Devices.  DLCI devices are
+ *             created for each DLCI associated with a FRAD.  The FRAD driver
+ *             is not truly a network device, but the lower level device
+ *             handler.  This allows other FRAD manufacturers to use the DLCI
+ *             code, including its RFC1490 encapsulation alongside the current
+ *             implementation for the Sangoma cards.
+ *
+ * Version:    @(#)if_ifrad.h  0.15    31 Mar 96
+ *
+ * Author:     Mike McLagan <mike.mclagan@linux.org>
+ *
+ * Changes:
+ *             0.15    Mike McLagan    changed structure defs (packed)
+ *                                     re-arranged flags
+ *                                     added DLCI_RET vars
