Working up from hardware capabilities and trying to generalize them probably won't lead anywhere. Do you have a model of the requirements for transport/device neutral QP prioritization that would meet your needs? _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
