                long: |
                    The MAVLink Mode defines the set of streamed messages (for example the
                    vehicle's attitude) and their sending rates.

            description:

                long: |
                    Configure the maximum sending rate for the MAVLink streams in Bytes/sec.
                    If the configured streams exceed the maximum rate, the sending rate of
                    each stream is automatically decreased.

                    If this is set to 0 a value of half of the theoretical maximum bandwidth is used.
                    This corresponds to baudrate/20 Bytes/s (baudrate/10 = maximum data rate on
                    8N1-configured links).

                long: |
                    If enabled, forward incoming MAVLink messages to other MAVLink ports if the
                    message is either broadcast or the target is not the autopilot.

                    This allows for example a GCS to talk to a camera that is connected to the
                    autopilot via MAVLink (on a different link than the GCS).

                    If enabled, MAVLink messages will be throttled according to
                    `txbuf` field reported by radio_status.

                    Requires a radio to send the mavlink message RADIO_STATUS.

                    This allows a ground control station to automatically find the drone
                    on the local network.

                    This is used to force flow control on or off for the the mavlink
                    instance. By default it is auto detected. Use when auto detection fails.

            type: enum
            values:

                    Positive real value that configures the transmission frequency of the
                    HIGH_LATENCY2 stream for instance ${i}, configured in iridium mode.
                    This parameter has no effect if the instance mode is different from iridium.
