在 ifconfig eth0 up 过程中，会打印错误日志，具体原因未知，还请晕哥等大神们指点一下。

这两条日志在经典的Linux 4.14 中也会打印出来。

这条日志在Linux 4.14 中没有，在Linux 6.10.3中会出现。

关于Linux 内核配置：

有线网卡驱动代码已经合入主线了，并不需要对代码进行修改，只需要配置内核即可。

1. Linux 6.10.3中没有“licheepi_zero_defconfig”，需要先从 Linux 5.2.x 中拷贝过来。
2. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- licheepi_zero_defconfig
3. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig 做如下修改：

关于Linux 设备树配置：

Linux 6.10.3中存在“sun8i-v3s-licheepi-zero.dts”设备树文件，只需要开启 “emac” 即可。

编译 & 烧录， 然后就可以愉快的上网了。

有可能是网线不好或者硬件问题

Re: 分享： V3S主线Linux 6.10.3有线网口调试记录

网线确定没有问题,用在其他设备或者电脑上都稳如老狗, 其他的话,硬件参考的荔枝派的电路图,照理说不应该有问题,布线用的PADS,tx和rx都是设置的差分布线,也没有大的转角,设计布线上应该问题也不大,电源用sy8079,可以输出2A电流,而且以前用在海思上也得到了验证,也不存在供电不足的情况,晕菜了

@wonrowl
检查下 EPHY-RTX 引脚的 电阻？  虽然不知道他是干啥的，但是各种开发板上都这样接的，我也这样搞上去了；  还有SZQ引脚，同样不知道是干啥的！
