* DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are |
|
* created for each DLCI associated with a FRAD. The FRAD driver |
|
* is not truly a network device, but the lower level device |
|
* handler. This allows other FRAD manufacturers to use the DLCI |
|
* code, including its RFC1490 encapsulation alongside the current |
|
* implementation for the Sangoma cards. |
|
* |
|
* Version: @(#)if_ifrad.h 0.15 31 Mar 96 |
|
* |
|
* Author: Mike McLagan <mike.mclagan@linux.org> |
|
* |
|
* Changes: |
|
* 0.15 Mike McLagan changed structure defs (packed) |
|
* re-arranged flags |
|
* added DLCI_RET vars |
