发送端执行
LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=benchmark_ker LSTACK_CONF_PATH=/etc/gazelle/lstack.conf ./benchmark_ker -sMode dn -pSize 0 -pdSize 0 -mSize 64 -tNums 2 -cNums 100 -cNb 1

接收端执行
LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=benchmark_ker LSTACK_CONF_PATH=/etc/gazelle/lstack.conf ./benchmark_ker -sMode dn -pSize 0 -pdSize 2 -mSize 64 -tNums 0 -cNums 0 -cNb 1

具体操作步骤
出现概率(是否必现，概率性错误) 100%

【预期结果】
可以正常打流

【实际结果】
No. 0, tid 36826, connect 100 successfully
