+ * That will then cause us here to set up a

+ * The alternative to this understanding is

+ * as a top field, but that's out of order
+ * since this driver always processes the top
+ * field first - the effect will be the two
+ * buffers being returned in the wrong order,
+ * with the second buffer also being delayed
+ * by one field time (owing to the fifo nature
+ * of videobuf). Worse still, we'll be stuck
+ * doing fields out of order now every time
+ * until something else causes a field to be
+ * dropped. By effectively forcing a field to
