如果不中断引导，进入系统后，网络使用正常。但在uboot里面无论如何都显示：No ethernet found.

使用的是官方下载下来的linux sdk代码，然后按照http://wiki.t-firefly.com/zh_CN/Firefly-RK3399/ubuntu_manual.html#wang-luo-qi-dong中的说法，kernel配置中使能nfs相关配置，更改dts中的bootargs并使能内核nfs相关配置。

现象依旧：
1、不中断内核引导，正常运行Linux，在Linux下eth0可以联网，没问题；
2、中断内核引导，进入u-boot命令行交互模式，则出现题述问题。
