/*
|

|
|
* 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
