Release 4.8 net/ipv4/ipconfig.c
/*
* Automatic Configuration of IP -- use DHCP, BOOTP, RARP, or
* user-supplied information to configure own IP address and routes.
*
* Copyright (C) 1996-1998 Martin Mares <mj@atrey.karlin.mff.cuni.cz>
*
* Derived from network configuration code in fs/nfs/nfsroot.c,
* originally Copyright (C) 1995, 1996 Gero Kuhlmann and me.
*
* BOOTP rewritten to construct and analyse packets itself instead
* of misusing the IP layer. num_bugs_causing_wrong_arp_replies--;
* -- MJ, December 1998
*
* Fixed ip_auto_config_setup calling at startup in the new "Linker Magic"
* initialization scheme.
* - Arnaldo Carvalho de Melo <acme@conectiva.com.br>, 08/11/1999
*
* DHCP support added. To users this looks like a whole separate
* protocol, but we know it's just a bag on the side of BOOTP.
* -- Chip Salzenberg <chip@valinux.com>, May 2000
*
* Ported DHCP support from 2.2.16 to 2.4.0-test4
* -- Eric Biederman <ebiederman@lnxi.com>, 30 Aug 2000
*
* Merged changes from 2.2.19 into 2.4.3
* -- Eric Biederman <ebiederman@lnxi.com>, 22 April Aug 2001
*
* Multiple Nameservers in /proc/net/pnp
* -- Josef Siemes <jsiemes@web.de>, Aug 2002
