- * @length:	Data length, i.e. the request's payload size in bytes

- *
- * This event is sent when the stack receives an incoming request to an address

- * guaranteed to be completely contained in the specified region.  Userspace is
- * responsible for sending the response by %FW_CDEV_IOC_SEND_RESPONSE ioctl,
- * using the same @handle.
- *
- * The payload data for requests carrying data (write and lock requests)
- * follows immediately and can be accessed through the @data field.
- *
- * Unlike &fw_cdev_event_request, @tcode of lock requests is one of the
- * firewire-core specific %TCODE_LOCK_MASK_SWAP...%TCODE_LOCK_VENDOR_DEPENDENT,
- * i.e. encodes the extended transaction code.
- *
- * @card may differ from &fw_cdev_get_info.card because requests are received
- * from all cards of the Linux host.  @source_node_id, @destination_node_id, and
- * @generation pertain to that card.  Destination node ID and bus generation may
- * therefore differ from the corresponding fields of the last
- * &fw_cdev_event_bus_reset.
- *
- * @destination_node_id may also differ from the current node ID because of a
- * non-local bus ID part or in case of a broadcast write request.  Note, a
- * client must call an %FW_CDEV_IOC_SEND_RESPONSE ioctl even in case of a
- * broadcast write request; the kernel will then release the kernel-side pending
- * request but will not actually send a response packet.
- *
- * In case of a write request to FCP_REQUEST or FCP_RESPONSE, the kernel already
- * sent a write response immediately after the request was received; in this
- * case the client must still call an %FW_CDEV_IOC_SEND_RESPONSE ioctl to
- * release the kernel-side pending request, though another response won't be
- * sent.
- *
- * If the client subsequently needs to initiate requests to the sender node of
- * an &fw_cdev_event_request2, it needs to use a device file with matching
- * card index, node ID, and generation for outbound requests.

- * @type:	See &fw_cdev_event_common; always %FW_CDEV_EVENT_ISO_INTERRUPT
- * @cycle:	Cycle counter of the last completed packet
- * @header_length: Total length of following headers, in bytes
- * @header:	Stripped headers, if any
- *
- * This event is sent when the controller has completed an &fw_cdev_iso_packet
- * with the %FW_CDEV_ISO_INTERRUPT bit set, when explicitly requested with
- * %FW_CDEV_IOC_FLUSH_ISO, or when there have been so many completed packets
- * without the interrupt bit set that the kernel's internal buffer for @header
- * is about to overflow.  (In the last case, kernels with ABI version < 5 drop
- * header data up to the next interrupt packet.)
- *
- * Isochronous transmit events (context type %FW_CDEV_ISO_CONTEXT_TRANSMIT):
- *
- * In version 3 and some implementations of version 2 of the ABI, &header_length
- * is a multiple of 4 and &header contains timestamps of all packets up until
- * the interrupt packet.  The format of the timestamps is as described below for
- * isochronous reception.  In version 1 of the ABI, &header_length was 0.
- *
- * Isochronous receive events (context type %FW_CDEV_ISO_CONTEXT_RECEIVE):
- *
- * The headers stripped of all packets up until and including the interrupt
- * packet are returned in the @header field.  The amount of header data per
- * packet is as specified at iso context creation by
- * &fw_cdev_create_iso_context.header_size.
- *
- * Hence, _interrupt.header_length / _context.header_size is the number of
- * packets received in this interrupt event.  The client can now iterate
- * through the mmap()'ed DMA buffer according to this number of packets and
- * to the buffer sizes as the client specified in &fw_cdev_queue_iso.
- *
- * Since version 2 of this ABI, the portion for each packet in _interrupt.header
- * consists of the 1394 isochronous packet header, followed by a timestamp
- * quadlet if &fw_cdev_create_iso_context.header_size > 4, followed by quadlets
- * from the packet payload if &fw_cdev_create_iso_context.header_size > 8.
- *
- * Format of 1394 iso packet header:  16 bits data_length, 2 bits tag, 6 bits
- * channel, 4 bits tcode, 4 bits sy, in big endian byte order.
- * data_length is the actual received size of the packet without the four
- * 1394 iso packet header bytes.
- *
- * Format of timestamp:  16 bits invalid, 3 bits cycleSeconds, 13 bits
- * cycleCount, in big endian byte order.
- *
- * In version 1 of the ABI, no timestamp quadlet was inserted; instead, payload
- * data followed directly after the 1394 is header if header_size > 4.
- * Behaviour of ver. 1 of this ABI is no longer available since ABI ver. 2.

- * %FW_CDEV_IOC_FLUSH_ISO.
- *
- * The buffer is continuously filled with the following data, per packet:
- *  - the 1394 iso packet header as described at &fw_cdev_event_iso_interrupt,
- *    but in little endian byte order,
- *  - packet payload (as many bytes as specified in the data_length field of

- *  - trailer quadlet, containing the reception timestamp as described at
- *    &fw_cdev_event_iso_interrupt, but in little endian byte order.
- *
- * Hence the per-packet size is data_length (rounded up to a multiple of 4) + 8.
- * When processing the data, stop before a packet that would cross the

- * are copied into the kernel and will not be accessed after the ioctl has
- * returned.
- *
- * The @control.SY and TAG fields are copied to the iso packet header.  These
- * fields are specified by IEEE 1394a and IEC 61883-1.
- *
- * The @control.SKIP flag specifies that no packet is to be sent in a frame.

- *
- * If the @control.SYNC flag is set, the context drops all packets until a

- * If more bytes are received, the additional bytes are dropped.  If less bytes

- *
- * Context type %FW_CDEV_ISO_CONTEXT_RECEIVE_MULTICHANNEL:
