struct fw_cdev_send_stream_packet - send an asynchronous stream packet : Length of outgoing payload, in bytes : Data format tag : Isochronous channel to transmit to : Synchronization code : Passed back to userspace in the response event : Userspace pointer to payload : The bus generation where packet is valid : Speed to transmit at
The FW_CDEV_IOC_SEND_STREAM_PACKET ioctl sends an asynchronous stream packet to every device which is listening to the specified channel. The kernel writes an &fw_cdev_event_response event which indicates success or failure of the transmission.
