Port remap

[embeddman]

Hi! I'm using KSZ9567R, in at91-sama5d3_xplained_ung8071.dts it's ports description like `ports {

address-cells = <1>;

                    #size-cells = <0>;
                    port@0 {
                        reg = <0>;
                        label = "lan1";
                    };
                    ...
                };`

How can I remap port order for example if I want to make 3rd physical switch port like 1st port of device?

The port is set by the "reg" parameter.

I tried the following config `ports {

address-cells = <1>;

                    #size-cells = <0>;
                    port@0 {
                        reg = <2>;
                        label = "lan1";
                    };
                    port@1 {
                        reg = <1>;
                        label = "lan2";
                    };
                    port@2 {
                        reg = <0>;
                        label = "lan3";
                    };
                    port@3 {
                        reg = <4>;
                        label = "lan4";
                    };
                    port@4 {
                        reg = <6>;
                        label = "lan5";
                    };
                    port@5 {
                        reg = <3>;
                        label = "lan6";                         
                    };
                    port@6 {
                        reg = <5>;
                        label = "cpu";
                        ethernet = <&macb0>;
                        fixed-link {
                            speed = <1000>;
                            full-duplex;
                        };                          
                    };
                };`. As I think reg values <0-6> should correspond to switch ports 1-7. But the upper config doesn't have effect. In sysfs I have the same /sys/class/net/eth0/sw0/0_... for 1-st switch port, not for 3-rd, as I thought. The same effect for dynamic mac table. What does it mean port remap?

These settings are only used in DSA driver. To remap ports you can change port_mappings inside the driver.
