+ * 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 protocol dispatcher.
+ *
+ * Version:	@(#)protocol.h	1.0.2	05/07/93

+ *					field for later.
+ *		Alan Cox	:	Cleaned up, and sorted types.
