| 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. |
