我们想将 mpc8308erdb 上的 vitesse 开关更改为 ks8999 开关。并将 eTSEC0 和 eTSEC1 连接到两个独立的 ks8999 交换机。
我想知道我应该更改哪些文件才能使 linux 在这种新条件下工作。这些交换机是快速以太网交换机，并通过 mii 接口连接到主板。（其中没有 mdio 接口）
我们像这样更改了设备树，并通过检查其他端口来检查交换机功能，但网络无法正常工作。未更改的设备树：

cell-index = <0>;
device_type = "network";
model = "eTSEC";

reg = <0x24000 0x1000>;
local-mac-address = [ 00 00 00 00 00 00 ];
interrupts = <32 0x8 33 0x8 34 0x8>;
interrupt-parent = <&ipic>;
tbi-handle = <&tbi0>;
phy-handle = < &phy0 >;
/* sleep = <&pmc 0xc0000000>; */

在参考板中，一个 eTSEC 连接到 phy，另一个 eTSEC 连接到千兆位以太网交换机。
