* @len: the length of data in the associated TD.
* @ntds_remaining: number of TDs (starting from this one) in this transfer.
*
+ * @bounce_buf: a bounce buffer if the std was from an urb with a sg
+ * list that could not be mapped to qTDs directly.
+ * @bounce_sg: the first scatterlist element bounce_buf is for.
+ * @bounce_offset: the offset into bounce_sg for the start of bounce_buf.
+ *
* Queued URBs may require more TDs than are available in a qset so we
* use a list of these "software TDs" (sTDs) to hold per-TD data.
