Alignment and line length. Also, you probably want to make all of those unsigned, otherwise you run into comparison warnings fast:    ```suggestion  #define SOMEIP_MAX_PLEN         (1400U) /**< SOME/IP maximum payload length */  /**   * @brief SOME/IP header length size, excluding payload   */  #define SOMEIP_HDR_LENGTH       (8U)  /**   * @brief SOME/IP full header size, including all fields except for the payload   */  #define SOMEIP_FULL_HDR_SIZE    (16U)  ```
