* lib/support.h This file contains the definitions of what is in the
* support library. Most of all, it defines structures
* for accessing support modules, and the function proto-
* types.
*
* NET-LIB A collection of functions used from the base set of the
* NET-3 Networking Distribution for the LINUX operating
* system. (net-tools, net-drivers)
*
* Version: lib/net-support.h 1.35 (1996-01-01)
*
* Maintainer: Bernd 'eckes' Eckenfels, <net-tools@lina.inka.de>

* Modifications:
*960125 {1.20} Bernd Eckenfels: reformated, layout
*960202 {1.30} Bernd Eckenfels: rprint in aftype
*960206 {1.31} Bernd Eckenfels: route_init
*960219 {1.32} Bernd Eckenfels: type for ap->input()
*960322 {1.33} Bernd Eckenfels: activate_ld and const in get_hwtype
*960413 {1.34} Bernd Eckenfels: new RTACTION suport
*990101 {1.35} Bernd Eckenfels: print_(hw|af)list support, added kerneldefines

/* ========== Kernel Defines =============
* Since it is not a good idea to depend on special kernel sources for the headers
* and since the libc6 Headers are not always up to date, we keep a copy of the
* most often used Flags in this file. We realy need a way to keep them up-to-date.
* Perhaps anybody knows how the glibc2 folk is doing it? -ecki
