./dpip route add 192.168.0.0/24 dev dpdk0
./dpip route add default via 192.168.0.10  dev dpdk0

./dpip route add 10.20.202.0/24 dev dpdk1

dpvs crash 的栈帧信息不全，请打开DEBUG 编译选项（在 config.mk 中配置 CONFIG_DEBUG=y），然后重新编译运行生成完整的crash 栈帧。

It seems the same problem as issue #911 . Please track the problem there. Closing this one.
