Actually... from the kernel, I think calling ib_create_qp() works with IB and RoCE, but not iWarp. You can still use the rdma_cm to connect, but transition the QPs yourself using rdma_init_qp_attr() and ib_modify_qp(). - Sean _______________________________________________ ewg mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
