| 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. | |

| 10 | * Version: @(#)if_ifrad.h 0.15 31 Mar 96 | |

| 12 | * Author: Mike McLagan <mike.mclagan@linux.org> | |

| 16 | * re-arranged flags | |
