+fixes:
+  - Fixes an issue which caused the DRAC driver (``pxe_drac``)
+    ``get_bios_config()`` vendor passthru method to unintentionally raise an
+    ``AttributeError`` exception. That method once again returns the current
+    BIOS configuration. For more information, see
+    https://bugs.launchpad.net/ironic/+bug/1637671.
