They are 10G capable. gem0: { fixed-link { speed = <1000>; full-duplex; }; phy0: phy@0: { reg = <0>; }; switch0: switch@1c: { compatible = "marvell,mv88e6190"; reg = <0x1c>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "cpu"; fixed-link { speed = <1000>; full-duplex; }; port@1 { reg = <1>; label = "lan0"; }; port@2 { reg = <2>; label = "lan1"; }; ... switch0port10: port@10 { reg = <10>; label = "dsa"; link = <&switch1port10>; phy-mode = "sgmii"; fixed-link { speed = <1000>; full-duplex; }; }; }; }; switch1: switch@1d: { compatible = "marvell,mv88e6190"; reg = <0x1d>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan9"; }; port@1 { reg = <1>; label = "lan10"; }; port@2 { reg = <2>; label = "lan11"; }; ... switch1port10: port@10 { reg = <10>; label = "dsa"; link = <&switch0port10>; phy-mode = "sgmii"; fixed-link { speed = <1000>; full-duplex; }; }; }; }; }; gem1: { phy-handle = <phy0>; }; It looks like you have at last one issue to solve in the macb driver. If you have a fixed-phy, it does an mdiobus_register. This means it is going to ignore all the other device tree properties. You need it to do an of_mdiobus_register(). Andrew
