630 * each frame is in the fields of the iso_frame-desc.
631 * @transfer_flags: A variety of flags may be used to affect how URB
632 * submission, unlinking, or operation are handled. Different
633 * kinds of URB can use different flags.
634 * @transfer_buffer: This identifies the buffer to (or from) which
635 * the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP
636 * is set). This buffer must be suitable for DMA; allocate it with
637 * kmalloc() or equivalent. For transfers to "in" endpoints, contents
638 * of this buffer will be modified. This buffer is used for the data
639 * stage of control transfers.
640 * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
641 * the device driver is saying that it provided this DMA address,
642 * which the host controller driver should use in preference to the
643 * transfer_buffer.
644 * @transfer_buffer_length: How big is transfer_buffer. The transfer may
645 * be broken up into chunks according to the current maximum packet
646 * size for the endpoint, which is a function of the configuration
647 * and is encoded in the pipe. When the length is zero, neither
648 * transfer_buffer nor transfer_dma is used.
649 * @actual_length: This is read in non-iso completion functions, and
650 * it tells how many bytes (out of transfer_buffer_length) were
651 * transferred. It will normally be the same as requested, unless
652 * either an error was reported or a short read was performed.
653 * The URB_SHORT_NOT_OK transfer flag may be used to make such
654 * short reads be reported as errors.
655 * @setup_packet: Only used for control transfers, this points to eight bytes
656 * of setup data. Control transfers always start by sending this data
657 * to the device. Then transfer_buffer is read or written, if needed.
65
658 * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
659 * device driver has provided this DMA address for the setup packet.
660 * The host controller driver should use this in preference to
661 * setup_packet.
662 * @start_frame: Returns the initial frame for isochronous transfers.
663 * @number_of_packets: Lists the number of ISO transfer buffers.
664 * @interval: Specifies the polling interval for interrupt or isochronous
665 * transfers. The units are frames (milliseconds) for for full and low
666 * speed devices, and microframes (1/8 millisecond) for highspeed ones.
667 * @error_count: Returns the number of ISO transfers that reported errors.
668 * @context: For use in completion functions. This normally points to
669 * request-specific driver context.
670 * @complete: Completion handler. This URB is passed as the parameter to the
671 * completion function. The completion function may then do what
672 * it likes with the URB, including resubmitting or freeing it.
