I don't think this is breaking anything, in premise all 3 CPU interfaces are completely interchangeable, with the notable fact that port 8 happens to have the flow accelerator block available for re-circulation of packets if we wanted to support a NATP offload at some point in the future. Vivek, maybe you can add ports 5 and 7 in the Device Tree and mark them as disabled for now. -- Florian _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
