  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.
