Wolfgang Denk:
Thanks a lot!
My bootargs is "setenv bootargs root=/dev/ram
ip=10.32.5.17:10.32.5.15::255.255.0.0:bug
:::off"
Today,I found fec device down when linux kernel running ,but I can see
"eth1(fec ethernet)" status with "ifconfig" command,I checked linux kernel and
found fec device down when kernel running.
After debugging,I found linux kernel close the device when running
"ip_auto_config()" function in "net/ipv4/ipconfig.c",then, I deleted
"ic_open_devs()" funtions, AND EVERYING
WORKS WELL!
But why do it be added to Linux kernel?
Best regards,
Michael. Z.
