245 * For some protocols, we store, in the packet_info structure, a pair

248 *
249 * This appears to have been done in order to allow protocols to save
250 * that information *without* overwriting the addresses or ports in the
251 * packet_info structure, so that the other code that uses those values,
252 * such as the code that fills in the address and port columns in the
253 * packet summary, will pick up the values put there by protocols such
254 * as IP and UDP, rather than the values put there by protocols such as
255 * TDMoP, FCIP, TIPC, and DVB Dynamic Mode Adaptation. See commit
256 * 66b441f3d63e21949530d672bf1406dea94ed254 and issue #11340.
257 *
258 * That is set by conversation_set_conv_addr_port_endpoints().
259 *
260 * In find_conversation_pinfo() and find_or_create_conversation(), if
261 * any dissector has set this, that address/port endpoint pair is used
262 * to look up or create the conversation.
263 *
264 * Prior to 4.0, conversations identified by a single integer value
265 * (such as a circuit ID) were handled by creating a pair of address/port
266 * endpoints with null addresses, the first port equal to the integer
267 * value, the second port missing, and a port type being an ENDPOINT_
268 * type specifying the protocol for the conversation. Now we use an
269 * array of elements, with a CE_UINT value for the integer followed
270 * by a CE_CONVERSATION_TYPE value specifying the protocol for the
271 * conversation.
272 *
273 * XXX - is there any reason why we shouldn't use an array of conversation
274 * elements, with the appropriate addresses and ports, instead of this
275 * structure? It would at least simplify find_conversation_pinfo() and
276 * find_or_create_conversation().
