Detailed Description

struct whc_std - a software TD. : the URB this sTD is for. : start of the URB's data for this TD. : the length of data in the associated TD. : number of TDs (starting from this one) in this transfer.

: a bounce buffer if the std was from an urb with a sg list that could not be mapped to qTDs directly. : the first scatterlist element bounce_buf is for. : 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.
