奇怪的现象
环境 Embedded Linux 2.6.34, busybox 1.17.2 。
没有废话，直接拷贝一个Commit log。
this condition is something strange, let me demostrate:
#ifconfig eth0 192.168.3.10
#ifconfig eth1 192.168.3.11
#ifconfig eth0 down
#ping 192.168.3.10
you will find the last ping still success even if you run it from another machine. To overcome this, you need to do:
#ifconfig eth0 0.0.0.0
before putting it down.
