不能设置eth0IP地址，但可以设置eth1的

板子启动后进入根文件，在设置IP地址的时候
#ifconfig eth0 192.168.1.100
PHY 1:01 not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)
ifconfig: SIOCSIFFLAGS: No such device

#ifconfig eth1 192.168.1.100
eth1: generated random MAC address 3e:58:5b:ff:47:e4
MACADDR in set is 3e:58:5b:ff:47:e4
# PHY: 1:02 - Link is Up - 100/Full
网上看到有说把eth1改为eth0的，

这里面没有相应的改动的地方，所以就没有修改了。
请问如何才能使eth1转为eth0,或者使用OK的eth1?
