Some host drivers such as NDIS (Network Driver Interface Specification) host drivers are
capable of concatenating small USB transfers (delta transfers) to form a single large USB
transfer. For OUT USB transfers, the device hardware has to break up this concatenated
transfer back into the original delta transfers and transfer them to separate DMA buffers.
This is achieved by setting the DMA mode to Auto Transfer Length Extraction (ATLE)
mode in the DMA descriptor. ATLE mode is supported for Bulk endpoints only.
