各位大师！
我用mini2440开发板挂载nfs的文件系统，内核打印信息提示“IP-Config: Device `eth0' not found”，我的nfs服务无法完成
一下是我的网络配置
u-boot里配置--
#define CONFIG_BOOTARGS "console=ttySAC0 root=/dev/nfs nfsroot=192.168.0.101:/opt/s3c2440/root_nfs ip=192.168.0.99:192.168.0.101:192.168.0.1:255.255.255.0:
www.sansung.com:eth0:off"
我的windons网络 192.168.1.70 255.255.255.0 192.168.1.1 dns = 192.168.1.1
我的linux网络 192.168.1.101 255.255.255.0 192.168.1.1 dns = 192.168.1.1
内核通过串口打印的信息为
