光口
- 我们自己做的底板，参照你们的开发板做了个万兆光口，但是硬件设计上是使用了你们原来的mac9(J5)万兆电口的引脚的。
如果直接使用1040_5599的配置网口是无法使用的，请问我的设备树和uboot的eth.c应该怎样修改？

- 我直接修改设备树，
ethernet@f0000 { /* 10GEC1 */
- //phy-handle = <&aqr105_phy>;
+ fixed-link = <0 1 1000 0 0>;
phy-connection-type = "xgmii";
};
/* - 禁用万兆mdio*/
// mdio@fd000 {
// aqr105_phy: ethernet-phy@0 {
// compatible = "ethernet-phy-ieee802.3-c45";
// reg = <0x0>;
// };
// };
更新到设备上后，fm1-mac9可以up起来，但是数据包发不出去，ping显示Destination Host Unreachable。
ethtool 显示如下内容：
root@localhost:~# ethtool fm1-mac9

哪里修改不对吗？还是漏了哪个地方没有修改？
