001: /*
002:  * DLCI/FRAD    Definitions for Frame Relay Access Devices.  DLCI devices are
003:  *              created for each DLCI associated with a FRAD.  The FRAD driver
004:  *              is not truly a network device, but the lower level device
005:  *              handler.  This allows other FRAD manufacturers to use the DLCI
006:  *              code, including its RFC1490 encapsulation alongside the current
007:  *              implementation for the Sangoma cards.
008:  *
009:  * Version:     @(#)if_ifrad.h  0.15    31 Mar 96
010:  *
011:  * Author:      Mike McLagan <mike.mclagan@linux.org>
012:  *
013:  * Changes:
014:  *              0.15    Mike McLagan    changed structure defs (packed)
015:  *                                      re-arranged flags
016:  *                                      added DLCI_RET vars
