The scenario you describe works fine for me.

Did you actually try interoperability between IPoIB with and without RC support? You might be pleasantly surprised. -- 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
