- * @type: One of the %_ODPL_* constants.
- * @port: Port that received the packet embedded in this message.
- * @arg: Argument value whose meaning depends on @type.
+ * struct odp_packet - header for packets passed up between kernel and
+ * userspace.
+ * @dp_idx: Number of datapath to which the packet belongs.
+ * @len: Length of complete message, including this header.
*
- * For @type == %_ODPL_MISS_NR, the header is followed by packet data. The
- * @arg member is the ID (in network byte order) of the tunnel that
- * encapsulated this packet. It is 0 if the packet was not received on a tunnel.
+ * The header is followed by a sequence of Netlink attributes. The
+ * %ODP_PACKET_ATTR_TYPE, %ODP_PACKET_ATTR_PACKET, and %ODP_PACKET_ATTR_KEY
+ * attributes are always present. When @type == %_ODPL_ACTION_NR, the
+ * %ODP_PACKET_ATTR_USERDATA attribute is included if it would be nonzero.
+ * When @type == %_ODPL_SFLOW_NR, the %ODP_PACKET_ATTR_SAMPLE_POOL and
+ * %ODP_PACKET_ATTR_ACTIONS attributes are included.
*
- * For @type == %_ODPL_ACTION_NR, the header is followed by packet data. The
- * @arg member is copied from the %ODPAT_CONTROLLER action that caused the
- * &struct odp_msg to be composed.
- *
- * For @type == %_ODPL_SFLOW_NR, the header is followed by &struct
- * odp_sflow_sample_header, then by a series of Netlink attributes (whose
- * length is specified in &struct odp_sflow_sample_header), then by packet
- * data.
+ * For @type of %_ODPL_ACTION_NR, %ODP_PACKET_ATTR_PACKET reflects changes made
+ * by actions preceding %ODPAT_CONTROLLER, but %ODP_PACKET_ATTR_KEY is the flow
+ * key extracted from the packet as originally received.
