+   * Callbacks for reporting debug ring buffer data.
+   *
+   * The ring buffer data collection is event based:
+   * - Driver calls this callback when new records are available, the
+   *   |WifiDebugRingBufferStatus| passed up to framework in the callback
+   *   indicates to framework if more data is available in the ring buffer.
+   *   It is not expected that driver will necessarily always empty the ring
+   *   immediately as data is available, instead driver will report data
+   *   every X seconds or if N bytes are available based on the parameters
+   *   set via |startLoggingToDebugRingBuffer|.
+   * - In the case where a bug report has to be captured, framework will
+   *   require driver to upload all data immediately. This is indicated to
+   *   driver when framework calls |forceDumpToDebugRingBuffer|.  The driver
+   *   will start sending all available data in the indicated ring by repeatedly
+   *   invoking this callback.
+   *
+   * @return status Status of the corresponding ring buffer. This should
+   *         contain the name of the ring buffer on which the data is
+   *         available.
+   * @return entries Vector of debug ring buffer data entries. These
+   *         should be parsed based on the type of entry.
