+ *
+ * The 'compat' member is special:

+ * - Most "struct ofpact"s correspond to one particular kind of OpenFlow

+ * 1.0.
+ *
+ * For such actions, the 'compat' member is not meaningful and generally
+ * should be zero.
+ *
+ * - A few "struct ofpact"s correspond to multiple OpenFlow actions. For
+ * example, OFPACT_SET_TUNNEL can be NXAST_SET_TUNNEL or
+ * NXAST_SET_TUNNEL64. In these cases, if the "struct ofpact" originated
+ * from OpenFlow, then we want to make sure that, if it gets translated
+ * back to OpenFlow later, it is translated back to the same action type.
+ * (Otherwise, we'd violate the promise made in DESIGN, in the "Action
+ * Reproduction" section.)
+ *
+ * For such actions, the 'compat' member should be the original action
+ * type. (If the action didn't originate from OpenFlow, then setting
+ * 'compat' to zero should be fine: code to translate the ofpact to
+ * OpenFlow must tolerate this case.)
