PHY: mdio@e0102120:03 - Link is Up - 100/Full

--- 192.168.111.69 ping statistics ---
35 packets transmitted, 0 packets received, 100% packet loss
哪位大神遇到相关问题，或者给提供点找这种问题的方法，多谢。

此贴没说明白问题，我想问的是ifconfig 如何找到那个网卡信息，能说明当前的MAC是配置正确的吗？ 还有就是在插网线的时候出现mdio@e0102120:03 - Link is Up - 100/Full能说明我的phy也是配置正确的吗？如何mac和phy都是正确的，如果网络还ping不通，该去哪里找问题？

这信息是什么鬼

那个111111111111111,5555555555是我调试加的信息，/*
3750  * ucc_geth_timeout gets called when a packet has not been
3751  * transmitted after a set amount of time.
3752  */
3753 static void ucc_geth_timeout(struct net_device *dev)
3754 {
3755         struct ucc_geth_private *ugeth = netdev_priv(dev);
3756
3757         netif_carrier_off(dev);
3758         printk("55555555555555555555555555555555555\n");
3759         schedule_work(&ugeth->timeout_work);
3760 }

那你的问题是什么，有点糊涂了

可以找打mac,可以找到phy,但ping不通。那个打印信息显示是超时，我不知道该怎么解决。。。。。回复 4# Godbach

网卡timeout是由软件watchdong触发的，通常意味着网卡dma队列已满，并且老的报文并没有及时发送出去。
可能的原因是，估计是tx相关的寄存器没有配置正确吧？ethtool -d可以导出寄存器的信息，参照一下芯片的spec，或者拿一个正常的设备做对比。
驱动的tx interrupt被触发过吗？

[找到问题了，我的设备树里的网卡信息可能配置的不全，我在uboot把这个网卡信息加一下就可以正常起来了。但按原理来说uboot可以没有这个网卡信息，设备树里加这个信息网卡也可以正常工作的，目前还没弄太清楚，只是板子能正常工作了

我还是每太弄明白到底少加了什么？
