What really should happen is that the field Local Ack Timeout in REQ should be (2 * PacketLifeTime + Local CA’s ACK delay) (see 12.7.34) and then the responder should use this for it's QP. This does not sound too hard - why can't we just fix CM to do this, then? -- MST _______________________________________________ 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
