 * INET		An implementation of the TCP/IP protocol suite for the LINUX

 *		Definitions for the UDP module.

 * Version:	@(#)udp.h	1.0.2	05/07/93

 * Authors:	Ross Biro, <bir7@leland.Stanford.Edu>
 *		Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>

 * Fixes:
 *		Alan Cox	: Turned on udp checksums. I don't want to
 *				  chase 'memory corruption' bugs that aren't!
