The spec isn't totally clear to me on this, but here's what I can gather: timewait = packet lifetime x 2 + remote ack delay local_ack_timeout (in CM REQ) = packet lifetime x 2 + local ack delay Verbs gets local_ack_timeout through qp_attr.timeout when modifying the QP to RTS. But from 12.7.34, I believe that the local_ack_timeout used by verbs is for the remote QP, meaning that: local_ack_timeout (verbs) = packet lifetime x 2 + remote ack delay which is also the timewait value. Do you concur? If so, then verbs already has the timewait value. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
