However, the netlink messages are only generated when the driver detects the link up/down event. For 3c59x driver, this is timer driven, so it might take some time (up to 60 seconds for MII capable cards) from the time the link has change state until the situation is detected. -- Bogdan Costescu IWR - Interdisziplinaeres Zentrum fuer Wissenschaftliches Rechnen Universitaet Heidelberg, INF 368, D-69120 Heidelberg, GERMANY Telephone: +49 6221 54 8869, Telefax: +49 6221 54 8868 E-mail: [email protected] _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
