 * lib/getroute.c     This file contains a small interface function to

 *                      table.
 *
 * 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)

 *
 *951020        Bernd Eckenfels:        creation
 *960202        Bernd Eckenfels:        rewrite to use getaftype.
 *960204        Bernd Eckenfels:        takes constant list of AFs
 *960206        Bernd Eckenfels:        route_init will enable routing
 *                                      support in the AF handlers
 *960221        Bernd Eckenfels:        renamed from route_info to getroute.c
 *960413        Bernd Eckenfels:        new RTACTION support
