 * Function: tiva_ethinitialize
 *
 * Description:
 *   Initialize the Ethernet driver for one interface.  If the Tiva/Stellaris
 *   chip supports multiple Ethernet controllers, then board specific logic
 *   must implement arm_netinitialize() and call this function to initialize
 *   the desired interfaces.
 *
 * Input Parameters:
 *   None
 *
 * Returned Value:
 *   OK on success; Negated errno on failure.
