1. Section 11.2.1.2 -- Query HCA: • The maximum number of scatter/gather entries per Work Re- quest supported by this HCA, for all Work Requests other than Reliable Datagram Receive Queue Work Requests. This certainly implies that the create verb should not return a number of scatter-gather entries greater than the max_sge value (which is the max value supported by this HCA). Otherwise, why have a max_sge value returned by Query HCA? What use would it serve? Furthermore, how can the HCA return an sge value in Create QP which exceeds the max_sge value returned by Query HCA? If it does, the sge value in Create QP should be the one returned in Query HCA! - Jack _______________________________________________ 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
