1 | /* |
| 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. | |
| 8 | * | |
| 9 | * Version: @(#)if_ifrad.h 0.15 31 Mar 96 | |
| 10 | * | |
| 11 | * Author: Mike McLagan <mike.mclagan@linux.org> | |
| 12 | * | |
| 13 | * Changes: | |
| 14 | * 0.15 Mike McLagan changed structure defs (packed) | |
| 15 | * re-arranged flags | |
| 16 | * added DLCI_RET vars | |
