+ *
+ * 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 OpenFlow type/code for each
+ * protocol that supports the error.
+ *
+ * - 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. */
