* @brief Test network device retrieval functions * * This function tests various methods to retrieve network devices: * - Get device by name (valid and invalid names) * - Get device by IP address (valid and invalid addresses) * - Get device by interface index (valid and invalid indices) * - Get first device by flags * - Get device by protocol family (if SAL is enabled) * * @note Tests bot

 * @note Tests both successful and failed retrieval scenarios
