        {"eth0", [
            {type, grisp_netman_ethernet},
            {ipv4, [
                {method, dhcp}
            ]}
        ]}
    ]}

{grisp_netman, [
    {interfaces, [
        {"eth0", [
            {type, grisp_netman_ethernet},
            {ipv4, [
                {method, static},
                {address, "192.168.2.100"},     % required
                {netmask, 24},                  % required
