DESCRIPTION
This library provides show routines for the shared memory network 
interface driver. 

The smNetShow() routine is provided as a diagnostic aid to show current
shared memory network status.

/*******************************************************************************
*
* smNetShow - show information about a shared memory network
*
* This routine displays information about the different CPUs configured
* in a shared memory network specified by <ifName>.  It prints error 
* statistics and zeros these fields if <zero> is set to TRUE.
*
* EXAMPLE
* .CS
*  -> smNetShow
*  Anchor at 0x800000
*  heartbeat = 705, header at 0x800010, free pkts = 237.
*
*  cpu int type    arg1       arg2       arg3    queued pkts
*  --- -------- ---------- ---------- ---------- -----------
*   0  poll            0x0        0x0        0x0       0
*   1  poll            0x0        0x0        0x0       0
*   2  bus-int         0x3       0xc9        0x0       0
*   3  mbox-2         0x2d     0x8000        0x0       0
*
*  input packets = 192     output packets = 164
*  output errors = 0       collisions = 0
*  value = 1 = 0x1
* .CE
*
* RETURNS: OK, or ERROR if there is a hardware setup problem or the routine
* cannot be initialized.
