We do not quite support that properly though, we still do not create a "cpu" network device, and there is only a single master netdev per dsa_switch at the moment, making the secondary CPU port interfaces impossible to overlay their backing "master" netdev with their companion switch port statistics at the moment. This fixes a real bug where we end-up clobbering dsa_cpu_port_ethtool_ops as soon as there are multiple trees being registered, and this can now happen. -- Florian
