As it says in the manual:SIOCGMIIPHY on 'eth?' failed: Operation not permitted  Most kernels restrict access to root.You need to run mii-tool as root, e.g. with sudo mii-tool.In general operation not permitted indicates a permission problem which is not related to file permissions. Often that means you need to be root.
