* Modified:
*
*960116 {1.01} Bernd Eckenfels: verbose, cleanups
*960204 {1.10} Bernd Eckenfels: aftrans, usage, new route_info,
* DLFT_AF
*960204 {1.11} Bernd Eckenfels: netlink support
*960204 {1.12} Bernd Eckenfels: route_init()
*960215 {1.13} Bernd Eckenfels: netlink_print honors HAVE_
*960217 {1.14} Bernd Eckenfels: masq_info from Jos Vos and
* ax25_info from Jonathan Naylor.
*960218 {1.15} Bernd Eckenfels: ipx_info rewritten, -e for tcp/ipx
*960220 {1.16} Bernd Eckenfels: minor output reformats, -a for -x
*960221 {1.17} Bernd Eckenfels: route_init->getroute_init
*960426 {1.18} Bernd Eckenfels: new RTACTION, SYM/NUM, FIB/CACHE
*960517 {1.19} Bernd Eckenfels: usage() spelling fix and --unix inode,
* ':' is part of sock_addr for --inet
*960822 {x.xx} Frank Strauss: INET6 support
*
*970406 {1.33} Philip Copeland Added snmp reporting support module -s
* code provided by Andi Kleen
* (relly needs to be kernel hooked but
* this will do in the meantime)
* minor header file misplacement tidy up.
*980815 {1.xx} Stephane Fillod: X.25 support
*980411 {1.34} Arnaldo Carvalho i18n: catgets -> gnu gettext, substitution
* of sprintf for snprintf
*10/1998 Andi Kleen Use new interface primitives.
*990101 {1.36} Bernd Eckenfels usage updated to include -s and -C -F,
* fixed netstat -rC output (lib/inet_gr.c)
* removed broken NETLINK Support
* fixed format for /proc/net/udp|tcp|raw
* added -w,-t,-u TcpExt support to -s
*990131 {1.37} Jan Kratochvil added -p for prg_cache() & friends
* Flames to <short@ucw.cz>.
* Tuan Hoang added IGMP support for IPv4 and IPv6
*
*990420 {1.38} Tuan Hoang removed a useless assignment from igmp_do_one()
*20010404 {1.39} Arnaldo Carvalho de Melo - use setlocale
*20081201 {1.42} Brian Micek added -L|--udplite options for RFC 3828
*20020722 {1.51} Thomas Preusser added SCTP over IPv4 support
