DESCRIPTION
This file is used to configure and initialize the VxWorks networking support
for remote I/O access. The file contents are added to the project 
configuration file when FOLDER_NET_REM_IO is included. It contains the 
initialization routine for the INCLUDE_NET_HOST_SETUP and INCLUDE_NET_REM_IO
components.

*
* usrNetHostSetup - final network initialization
*
* This routine performs the setup which follows any device initialization
* and/or verification of the boot line. It adds any necessary host and 
* gateway entries, analogous to /etc/hosts and /etc/gateways in UNIX systems. 
* It is called by the configuration tool as the component initialization 
* routine for INCLUDE_NET_HOST_SETUP. Any network remote I/O device can be 
* added after this routine is complete.
* 
* RETURNS:
* OK, or
* ERROR if there is a problem in the boot string, or initializing network.
