31 * This macro is used directly only internally by this header, but the list is
32 * still of interest to developers.
34 * Each DEFINE_OFPACT invocation has the following parameters:
36 * 1. <ENUM>, used below in the enum definition of OFPACT_<ENUM>, and
39 * 2. <STRUCT> corresponding to a structure "struct <STRUCT>", that must be
40 * defined below. This structure must be an abstract definition of the
41 * action. Its first member must have type "struct ofpact" and name
42 * "ofpact". It may be fixed length or end with a flexible array member
43 * (e.g. "int member[];").
45 * 3. <MEMBER>, which has one of two possible values:
47 * - If "struct <STRUCT>" is fixed-length, it must be "ofpact".
49 * - If "struct <STRUCT>" is variable-length, it must be the name of the
50 * flexible array member.

127 * Each action is a structure "struct ofpact_*" that begins with "struct

129 * are padded out to a multiple of OFPACT_ALIGNTO bytes in length.
131 * The 'compat' member is special:
133 * - Most "struct ofpact"s correspond to one particular kind of OpenFlow
134 * action, at least in a given OpenFlow version. For example,
135 * OFPACT_SET_VLAN_VID corresponds to OFPAT10_SET_VLAN_VID in OpenFlow
138 * For such actions, the 'compat' member is not meaningful and generally
141 * - A few "struct ofpact"s correspond to multiple OpenFlow actions. For
142 * example, OFPACT_SET_TUNNEL can be NXAST_SET_TUNNEL or
143 * NXAST_SET_TUNNEL64. In these cases, if the "struct ofpact" originated
144 * from OpenFlow, then we want to make sure that, if it gets translated
145 * back to OpenFlow later, it is translated back to the same action type.
146 * (Otherwise, we'd violate the promise made in DESIGN, in the "Action
147 * Reproduction" section.)
149 * For such actions, the 'compat' member should be the original action
150 * type. (If the action didn't originate from OpenFlow, then setting

152 * OpenFlow must tolerate this case.)
