/*
 * 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 <[email protected]>
 *
 * Changes:
 *      0.15    Mike McLagan    changed structure defs (packed)
 *                  re-arranged flags
 *                  added DLCI_RET vars
