Data Fields
const uint8_t *	buffer
	Start of buffer for transfer.

uint32_t	length
	Total number of bytes to be transferred to/from buffer.

uint32_t	offset
	Byte offset of the next packet to be transferred.

usb_testutils_xfr_flags_t	flags
	Flags modifying the transfer.

bool	last
	Indicates that the last packet of the transfer has been reached; if 'next_valid' is true, then 'next_part' holds the last packet, already prepared for sending; if next_valid is false, then the last packet has already been supplied to usbdev and we're just awaiting the 'pkt_sent' interrupt.

bool	next_valid
	The next part has been prepared and is ready to send to usbdev.

dif_usbdev_buffer_t	next_part
	When sending IN data to the host, we may employ double-buffering and keep an additional buffer ready to be sent as soon as we're notified of the transfer of its predecessor.
