I think that all iWARP devices encode their MAC in index0 of their gid table. You can look for a matching RDMA device by querying its gids.

Another semi-ugly way to do it is to look at the /sys/class/net/ethX/device link and then look at the /sys/class/infiniband/xxx/device links and see if it is the same. any _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
