+ * 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 IP protocol.
+ *
+ * Version:     @(#)ip.h        1.0.2   04/28/93
