+ * --------------------
+ *
+ * The comments below are parsed by the extract-ofp-errors program at build
+ * time and used to determine the mapping between "enum ofperr" constants and
+ * error type/code values used in the OpenFlow protocol:
+ *
+ *   - The first part of each comment specifies the vendor, OpenFlow versions,
+ *     type, and sometimes a code for each protocol that supports the error:
+ *
+ *         # The vendor is OF for standard OpenFlow error codes.  Otherwise it
+ *           is one of the *_VENDOR_ID codes defined in openflow-common.h.
+ *
+ *         # The version can specify a specific OpenFlow version, a version
+ *           range delimited by "-", or an open-ended range with "+".
+ *
+ *         # Standard OpenFlow errors have both a type and a code.  Extension
+ *           errors generally have only a type, no code.  There is one
+ *           exception: Nicira extension (NX) errors for OpenFlow 1.0 and 1.1
+ *           have both a type and a code.  (This means that the version
+ *           specification for NX errors may not include version 1.0 or 1.1 (or
+ *           both) along with version 1.2 or later, because the requirements
+ *           for those versions are different.)
+ *
+ *   - Additional text is a human-readable description of the meaning of each
+ *     error, used to explain the error to the user.  Any text enclosed in
+ *     square brackets is omitted; this can be used to explain rationale for
+ *     choice of error codes in the case where this is desirable.
+ *
+ *
+ * Expected duplications
+ * ---------------------
+ *
+ * Occasionally, in one version of OpenFlow a single named error can indicate
+ * two or more distinct errors, then a later version of OpenFlow splits those
+ * meanings into different error codes.  When that happens, both errors are
+ * assigned the same value in the earlier version.  That is ordinarily a
+ * mistake, so the build system reports an error.  When that happens, add the
+ * error message to the list of "Expected duplications" below to suppress the
+ * error.  In such a case, the named error defined earlier is how OVS
+ * interprets the earlier, merged form of the error.
+ *
+ * For example, OpenFlow 1.1 defined (3,5) as OFPBIC_UNSUP_EXP_INST, then
+ * OpenFlow 1.2 broke this error into OFPBIC_BAD_EXPERIMENTER as (3,5) and
+ * OFPBIC_BAD_EXT_TYPE as (3,6).  To allow the OVS code to report just a single
+ * error code, instead of protocol version dependent errors, this list of
+ * errors only lists the latter two errors, giving both of them the same code
+ * (3,5) for OpenFlow 1.1.  Then, when OVS serializes either error into
+ * OpenFlow 1.1, it uses the same code (3,5).  In the other direction, when OVS
+ * deserializes (3,5) from OpenFlow 1.1, it translates it into
+ * OFPBIC_BAD_EXPERIMENTER (because its definition precedes that of
+ * OFPBIC_BAD_EXT_TYPE below).  See the "encoding OFPBIC_* experimenter errors"
+ * and "decoding OFPBIC_* experimenter errors" tests in tests/ofp-errors.at for
+ * full details.

-/* OpenFlow error codes
- * --------------------
- *
- * The comments below are parsed by the extract-ofp-errors program at build
- * time and used to determine the mapping between "enum ofperr" constants and
- * error type/code values used in the OpenFlow protocol:
- *
- *   - The first part of each comment specifies the vendor, OpenFlow versions,
- *     type, and sometimes a code for each protocol that supports the error:
- *
- *         # The vendor is OF for standard OpenFlow error codes.  Otherwise it
- *           is one of the *_VENDOR_ID codes defined in openflow-common.h.
- *
- *         # The version can specify a specific OpenFlow version, a version
- *           range delimited by "-", or an open-ended range with "+".
- *
- *         # Standard OpenFlow errors have both a type and a code.  Extension
- *           errors generally have only a type, no code.  There is one
- *           exception: Nicira extension (NX) errors for OpenFlow 1.0 and 1.1
- *           have both a type and a code.  (This means that the version
- *           specification for NX errors may not include version 1.0 or 1.1 (or
- *           both) along with version 1.2 or later, because the requirements
- *           for those versions are different.)
- *
- *   - Additional text is a human-readable description of the meaning of each
- *     error, used to explain the error to the user.  Any text enclosed in
- *     square brackets is omitted; this can be used to explain rationale for
- *     choice of error codes in the case where this is desirable.
- *
- *
- * Expected duplications
- * ---------------------
- *
- * Occasionally, in one version of OpenFlow a single named error can indicate
- * two or more distinct errors, then a later version of OpenFlow splits those
- * meanings into different error codes.  When that happens, both errors are
- * assigned the same value in the earlier version.  That is ordinarily a
- * mistake, so the build system reports an error.  When that happens, add the
- * error message to the list of "Expected duplications" below to suppress the
- * error.  In such a case, the named error defined earlier is how OVS
- * interprets the earlier, merged form of the error.
- *
- * For example, OpenFlow 1.1 defined (3,5) as OFPBIC_UNSUP_EXP_INST, then
- * OpenFlow 1.2 broke this error into OFPBIC_BAD_EXPERIMENTER as (3,5) and
- * OFPBIC_BAD_EXT_TYPE as (3,6).  To allow the OVS code to report just a single
- * error code, instead of protocol version dependent errors, this list of
- * errors only lists the latter two errors, giving both of them the same code
- * (3,5) for OpenFlow 1.1.  Then, when OVS serializes either error into
- * OpenFlow 1.1, it uses the same code (3,5).  In the other direction, when OVS
- * deserializes (3,5) from OpenFlow 1.1, it translates it into
- * OFPBIC_BAD_EXPERIMENTER (because its definition precedes that of
- * OFPBIC_BAD_EXT_TYPE below).  See the "encoding OFPBIC_* experimenter errors"
- * and "decoding OFPBIC_* experimenter errors" tests in tests/ofp-errors.at for
- * full details.
