 * 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.

 *

 *              Various kernel-resident INET utility functions; mainly

 *              for format conversion and debugging output.
