+ * Now we need to find out what the last successful toggle was
+ * so we can update the local data toggle for the next transfer
+ *
+ * There are 2 ways the last successful completed TD is found:
+ *
+ * 1) The TD is NOT active and the actual length < expected length
+ * 2) The TD is NOT active and it's the last TD in the chain
+ *
+ * and a third way the first uncompleted TD is found:
+ *
+ * 3) The TD is active and the previous TD is NOT active
+ *
+ * Control and Isochronous ignore the toggle, so this is safe
+ * for all types
+ *
+ * FIXME: The toggle fixups won't be 100% reliable until we
+ * change over to using a single queue for each endpoint and
+ * stop the queue before unlinking.
