Only thing consistent is PCI config space - assuming the PCI bus numbers don't change. Look at pciutils to see how and what it supports. hth, grant _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
