+ * @param ScanDuration Value used to calculate the length of time to
+ * spend scanning each channel for ED, active, and
+ * passive scans. This parameter is ignored for
+ * orphan scans.
+ * @param ChannelPage The channel page on which to perform the scan
+ * @param EnergyDetectListNumEntries The number of entries in the
+ * <tt>EnergyDetectList</tt>.
+ * @param EnergyDetectList An empty buffer (allocated by the caller)
+ * to store the result of the energy measurements

+ * <tt>PANDescriptorList</tt>.
+ * @param PANDescriptorList An empty buffer (allocated by the caller)

+ * or NULL if the result should not be stored
+ * @param security The security options (NULL means security is
+ * disabled)
+ * @return IEEE154_SUCCESS if the request succeeded and a confirm event
