+ * - __u8
+ - ``msg[16]``
+ - The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
+ application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+ For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
+ the payload of the reply message if ``timeout`` was set.
+ * - __u8
+ - ``reply``
+ - Wait until this message is replied. If ``reply`` is 0 and the
+ ``timeout`` is 0, then don't wait for a reply but return after
+ transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+ The case where ``reply`` is 0 (this is the opcode for the Feature Abort
+ message) and ``timeout`` is non-zero is specifically allowed to make it
+ possible to send a message and wait up to ``timeout`` milliseconds for a
+ Feature Abort reply. In this case ``rx_status`` will either be set
+ to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
+ :ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
+ * - __u8
+ - ``rx_status``
+ - The status bits of the received message. See
+ :ref:`cec-rx-status` for the possible status values. It is 0 if
+ this message was transmitted, not received, unless this is the
+ reply to a transmitted message. In that case both ``rx_status``
+ and ``tx_status`` are set.
+ * - __u8
+ - ``tx_status``
+ - The status bits of the transmitted message. See
+ :ref:`cec-tx-status` for the possible status values. It is 0 if
+ this messages was received, not transmitted.
+ * - __u8
+ - ``tx_arb_lost_cnt``
+ - A counter of the number of transmit attempts that resulted in the
+ Arbitration Lost error. This is only set if the hardware supports
+ this, otherwise it is always 0. This counter is only valid if the
+ :ref:`CEC_TX_STATUS_ARB_LOST <CEC-TX-STATUS-ARB-LOST>` status bit is set.
+ * - __u8
+ - ``tx_nack_cnt``
+ - A counter of the number of transmit attempts that resulted in the
+ Not Acknowledged error. This is only set if the hardware supports
+ this, otherwise it is always 0. This counter is only valid if the
+ :ref:`CEC_TX_STATUS_NACK <CEC-TX-STATUS-NACK>` status bit is set.
+ * - __u8
+ - ``tx_low_drive_cnt``
+ - A counter of the number of transmit attempts that resulted in the
+ Arbitration Lost error. This is only set if the hardware supports
+ this, otherwise it is always 0. This counter is only valid if the
+ :ref:`CEC_TX_STATUS_LOW_DRIVE <CEC-TX-STATUS-LOW-DRIVE>` status bit is set.
+ * - __u8
+ - ``tx_error_cnt``
+ - A counter of the number of transmit errors other than Arbitration
+ Lost or Not Acknowledged. This is only set if the hardware
+ supports this, otherwise it is always 0. This counter is only
+ valid if the :ref:`CEC_TX_STATUS_ERROR <CEC-TX-STATUS-ERROR>` status bit is set.
