KSZ9031RNXIC interface with imx8mq , 1000MBPS not working

[saurav-pandya]

Hi ,

I am working on imx8mq custom board. I am working to interface KSZ9031RNXIC with imx8mq.

Device tree configuration 

&fec1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_fec1>;
phy-reset-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
phy-mode = "rgmii-id";
phy-handle = <&ethphy3>;
fsl,magic-packet;
status = "okay";

mdio {
#address-cells = <1>;
#size-cells = <0>;

ethphy3: ethernet-phy@3 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <3>;
//max-speed = <100>;
//at803x,eee-disabled;
};
};
};

We did't get ip when we have configured interface speed 1000MBPS.

Please help me to resolve this issue.

Thanks,
