+/****************************************************************************
+ * Name: xhci_interval
+ *
+ * Description:
+ *   Work out the Interval an endpoint context wants.
+ *
+ *   The field is an exponent: the controller services the endpoint every
+ *   2^Interval microframes.  An endpoint descriptor does not say it that
+ *   way, and what it does say depends on how fast the device is, so the
+ *   number cannot simply be copied across.
+ *
+ *   A low or full speed interrupt endpoint counts in frames, so its period
+ *   is bInterval milliseconds, or bInterval * 8 microframes, and the
+ *   exponent is the position of the highest bit of that.  Everything else
+ *   that is periodic already states an exponent, one greater than the one
+ *   wanted here.  Control and bulk endpoints are not periodic and the field
+ *   means nothing to them.
+ *
