/*
DESCRIPTION
This library provides routines to show various network-related
statistics, such as configuration parameters for network interfaces,
protocol statistics, socket statistics, and so on.

Interpreting these statistics requires detailed knowledge of Internet
network protocols.  Information on these protocols can be found in
the following books:
.iP
.I "Internetworking with TCP/IP Volume III,"
by Douglas Comer and David Stevens
.iP
.I "UNIX Network Programming,"
by Richard Stevens
.iP
.I "The Design and Implementation of the 4.3 BSD UNIX Operating System,"
by Leffler, McKusick, Karels and Quarterman

.LP
The netShowInit() routine links the network show facility into the VxWorks
system.  This is performed automatically if INCLUDE_NET_SHOW is defined.
If you want inetstatShow() to display TCP socket status, then INCLUDE_TCP_SHOW
needs to be included.


INTERNAL
Some routines within this module are preempted by parallel versions
built in to the Tornado shell source code in the $WIND_BASE/host/src/windsh
directory. Changes to these routines must be duplicated within the shell to
maintain consistent output. The versions in this module can still be
accessed by prepending an "@" sign to the routine name (e.g. "@ifShow").

Currently, the following routines are preempted:

     ifShow, inetstatShow, ipstatShow, routestatShow, hostShow

SEE ALSO: ifLib, icmpShow, igmpShow, tcpShow, udpShow

* ifShow - display the attached network interfaces
*
* This routine displays the attached network interfaces for debugging and
* diagnostic purposes.  If <ifName> is given, only the interfaces belonging
* to that group are displayed.  If <ifName> is omitted, all attached
* interfaces are displayed.
*
* For each interface selected, the following are shown: Internet
* address, point-to-point peer address (if using SLIP), broadcast address,
* netmask, subnet mask, Ethernet address, route metric, maximum transfer
* unit, number of packets sent and received on this interface, number of
* input and output errors, and flags (such as loopback, point-to-point,
* broadcast, promiscuous, ARP, running, and debug).
*
* EXAMPLE:
* The following call displays all interfaces whose names begin with "ln",
* (such as "ln0", "ln1", and "ln2"):
* .CS
*     -> ifShow "ln"
* .CE
* The following call displays just the interface "ln0":
* .CS
*     -> ifShow "ln0"
* .CE
*
* RETURNS: N/A
*
* SEE ALSO: routeShow(), ifLib
*
* INTERNAL
* When using the Tornado shell, this routine is only available if an
* "@" sign is prepended to the routine name. Otherwise, it is preempted
* by a built-in version.
