True, but the description for the CM REJ code 26 for Invalid Path MTU states something a little different (p. 667): "The recepient of the REQ message cannot support the maximum packet payload size requested." is being interpreted as "prefers not to support the max payload size requested" which is probably OK. > I guess the question is what to do when a Tavor (with the performance > bug that makes a 1K MTU faster) connects to someone else. Isn't it the other way 'round (when something with a larger MTU connects to Tavor) ? -- Hal > - R. > _______________________________________________ > openib-general mailing list > [email protected] > http://openib.org/mailman/listinfo/openib-general > > To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
