I wonder if it's worth it... the alternative would be for cxgb3 etc. to just return STag 0 from get_dma_mr if only local access rights are requested. But of course as we discussed later STag 0 doesn't do PD protection, if anyone cared. We can always change it later anyway. - R. _______________________________________________ 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
