-/*
- * 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.
- *
- * Definitions for the AF_INET socket handler.
- *
- * Version: @(#)sock.h 1.0.4 05/13/93
- *
- * Authors: Ross Biro, <bir7@leland.Stanford.Edu>
- * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
- * Corey Minyard <wf-rch!minyard@relay.EU.net>
- * Florian La Roche <flla@stud.uni-sb.de>
- *
- * Fixes:
- * Alan Cox : Volatiles in skbuff pointers. See
- * skbuff comments. May be overdone,
- * better to prove they can be removed
- * than the reverse.
- * Alan Cox : Added a zapped field for tcp to note
- * a socket is reset and must stay shut up
- * Alan Cox : New fields for options
- * Pauline Middelink : identd support
- *
