随驱动附带的run_test.sh是否能满足测试要求？
在run_test.sh脚本中测试为“固定次数”的收发，如下命令 ./dma_streaming_test.sh $transferSize $transferCount $channelPairs 是不是不能满足长期运行测试的要求（都是指定循环次数）？ 自己修改了dma_from_device.c(添加无限制循环写)，对侧dma_to_device.c也作相似修改后，循环收发（读写）指定固定格式帧（为了校验）时，会存在误码问题（即几千次后的某一帧/包，会存在误码, 这个包越大出现的情况越大，小包长度2k以下好像未发现）。
#当4通道并发读写导出驱动crash. 日志提示如下，这是否与硬件相关？还是驱动自身BUG？内核日志如下：
