Tool/software: TI C/C++ Compiler

HI ,  I　use the rgmii1  port  connect to BCM89811,and my dts is like this,

 DTS:

&mac {
status = "okay";
dual_emac;
};
&davinci_mdio {
status = "okay";
};

&cpsw_emac0 {
phy_id = <&davinci_mdio>, <0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <2>;
};

&cpsw_emac1 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
};

I  set the command "ifconfig eth0 192.168.208.110 up" then  look the kernel message:

[ 70.109299] net eth0: initializing cpsw version 1.15 (0)
[ 70.109315] net eth0: initialized cpsw ale version 1.4
[ 70.109325] net eth0: ALE Table size 1024
[ 70.116837] net eth0: phy found : id is : 0xae025022
[ 70.123702] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready

why my eth0 is link is not well   wrok?

    Have you tried ethtool to change the speed/duplexity ?
