   2  * INET         An implementation of the TCP/IP protocol suite for the LINUX
   3  *              operating system.  INET is implemented using the  BSD Socket
   4  *              interface as the means of communication with the user level.
   5  *
   6  *              General Definitions for the TCP/IP (INET) module. This is
   7  *              mostly a bunch of "general" macros, plus the PROTOCOL link
   8  *              code and data.
