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.
