DESCRIPTION
This file is used to configure and initialize the VxWorks networking support.
The file is included in the project configuration file when INCLUDE_NET_SETUP 
is defined. It creates the network memory pools and the device control 
structure used by both END and BSD style drivers. It also initializes the 
interface index library.
