/*
 * INET         An implementation of the TCP/IP protocol suite for the LINUX
 *              operating system.  INET is implemented using the  BSD Socket
 *              interface as the means of communication with the user level.
 *
 *              RAW - implementation of IP "raw" sockets.
 *
 * Authors:     Ross Biro
 *              Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
 *
 * Fixes:
 *              Alan Cox        :       verify_area() fixed up
 *              Alan Cox        :       ICMP error handling
 *              Alan Cox        :       EMSGSIZE if you send too big a packet
 *              Alan Cox        :       Now uses generic datagrams and shared
 *                                      skbuff library. No more peek crashes,
 *                                      no more backlogs
 *              Alan Cox        :       Checks sk->broadcast.
 *              Alan Cox        :       Uses skb_free_datagram/skb_copy_datagram
 *              Alan Cox        :       Raw passes ip options too
 *              Alan Cox        :       Setsocketopt added
 *              Alan Cox        :       Fixed error return for broadcasts
 *              Alan Cox        :       Removed wake_up calls
 *              Alan Cox        :       Use ttl/tos
 *              Alan Cox        :       Cleaned up old debugging
 *              Alan Cox        :       Use new kernel side addresses
 *      Arnt Gulbrandsen        :       Fixed MSG_DONTROUTE in raw sockets.
 *              Alan Cox        :       BSD style RAW socket demultiplexing.
 *              Alan Cox        :       Beginnings of mrouted support.
 *              Alan Cox        :       Added IP_HDRINCL option.
 *              Alan Cox        :       Skip broadcast check if BSDism set.
 *              David S. Miller :       New socket lookup architecture.
