NCSI eth0 (ftgmac100): transmit queue 0 timed out error

[xiuzhi]

Hi all,
   I set the  eth0/MAC#1 of Ast2500 to NCSI mode.
There is a on-off switch between Ast2500 MAC#1 and host Network. 
 The hardware electrical signal is good and can ping to other machines on AMI BMC
.dts:
 &mac0 {
        status = "okay";
  
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_rgii1_default>;
        use-ncsi;
};
