 * transfer wrapper. The transfers wrapper are continually reused for
 * the Interrupt and Isochronous pipes as those pipes are polled.
 *
 * Control, bulk and interrupt transfers will have one DMA buffer per
 * transfer. The data to be transferred are contained in the DMA buffer
 * which is virtually contiguous but physically discontiguous. When
 * preparing the TDs for a USB transfer, the DMA cookies contained in
 * the buffer need to be walked through to retrieve the DMA addresses.
 *
 * Isochronous transfers will have multiple DMA buffers per transfer
 * with each isoc packet having a DMA buffer. And the DMA buffers should
 * only contain one cookie each, so no cookie walking is necessary.
