   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  *              This file implements the various access functions for the
   7  *              PROC file system.  This is very similar to the IPv4 version,
   8  *              except it reports the sockets in the INET6 address family.
