* Name: net_setup
*
* Description:
* This is called from the OS initialization logic at power-up reset in
* order to configure networking data structures. This is called prior
* to platform-specific driver initialization so that the networking
* subsystem is prepared to deal with network driver initialization
* actions.
*
* Actions performed in this initialization phase assume that base OS
* facilities such as semaphores are available but this logic cannot
* depend upon OS resources such as interrupts or timers which are not
* yet available.
*
* Input Parameters:
* None
*
* Returned Value:
* None
