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.
9 * Version: @(#)if_ifrad.h 0.15 31 Mar 96
11 * Author: Mike McLagan <mike.mclagan@linux.org>
13 * Changes:
14 * 0.15 Mike McLagan changed structure defs (packed)
15 * re-arranged flags
16 * added DLCI_RET vars
