-/* OpenFlow errors.
- *
- * OpenFlow errors have two 16-bit parts: a "type" and a "code". A "type" has
- * a unique meaning. The "code" values are different for each "type".
- *
- * We embed OpenFlow errors in the same space as errno values by shifting
- * 'type' left 16 bits and adding the 'code'. An "int" value is thus broken
- * into a few different ranges:
+/* Actions. */
+
+/* The type of an action.
*
- * - 0: success.
+ * For each implemented OFPAT_* and NXAST_* action type, there is a
+ * corresponding constant prefixed with OFPUTIL_, e.g.:
*
- * - 1...65535: system errno values.
+ * OFPUTIL_OFPAT_OUTPUT
+ * OFPUTIL_OFPAT_SET_VLAN_VID
+ * OFPUTIL_OFPAT_SET_VLAN_PCP
+ * OFPUTIL_OFPAT_STRIP_VLAN
+ * OFPUTIL_OFPAT_SET_DL_SRC
+ * OFPUTIL_OFPAT_SET_DL_DST
+ * OFPUTIL_OFPAT_SET_NW_SRC
+ * OFPUTIL_OFPAT_SET_NW_DST

- * The assumption that system errno values are less than 65536 is true
- * on at least Linux, FreeBSD, OpenBSD, and Windows. RFC 1813 defines
- * NFSv3-specific errno codes starting at 10000, another hint that this
