I'm starting to get lost here. Are you concerned that the SM will change the MTU or rate of a path, and the caches will not be updated? What about existing connections? I see that either the SA can use events to notify end nodes when such a situation arises, or the end nodes can poll for changes. The former isn't spec'ed, but the later can be done using the ib_local_sa's /sys/class interface. - Sean _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
