 * Name: net_initialize
 *
 * 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
 *
