 * lib/support.h      This file contains the definitions of what is in the

 *                      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)

 *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
