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