3  * DLCI/FRAD	Definitions for Frame Relay Access Devices.  DLCI devices are
4  *		created for each DLCI associated with a FRAD.  The FRAD driver
5  *		is not truly a network device, but the lower level device
6  *		handler.  This allows other FRAD manufacturers to use the DLCI
7  *		code, including its RFC1490 encapsulation alongside the current
8  *		implementation for the Sangoma cards.
