解决方案

This is a known issue in the 2019.1 VCU118 PetaLinux BSP.

To work around this issue, add the below device-tree properties to the phy node in <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

 
/include/ "system-conf.dtsi"
/{
};
 
&axi_ethernet_0 {
    axi_ethernet_mdio: mdio {
        phy0: phy@3 {
    ti,rx-internal-delay = <0x8>;
            ti,tx-internal-delay = <0xa>;
            ti,fifo-depth = <0x1>;
        };
    };
};
