If a device is added to a bond or bridge, the disable_ipv6 sysctl is set, so that no link local addresses are present on the slave devices. However, the disable_ipv6 sysctl is not restored after removing the device from the bridge or bond. Therefore, no IPv6 link local addresses are added and autoconfiguration does not work. Set the disable_ipv6 to '0' on device removal from bridge or bond. Signed-off-by: Fabian Bläse <fabian@blaese.de>
