cregit-Linux how code gets into the kernel

Release 4.12 include/uapi/linux/if_frad.h

 * 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 <>
 * Changes:
 *              0.15    Mike McLagan    changed structure defs (packed)
 *                                      re-arranged flags
 *                                      added DLCI_RET vars
 *              This program is free software; you can redistribute it and/or
