RE: [EXT] [PATCH v6] app/dma-perf: introduce dma-perf application

Hi Cheng,

I think there is a bug in EAL parsing. Please check the below diff and see if 
we should do something similar.

diff --git a/app/test-dma-perf/main.c b/app/test-dma-perf/main.c
index d65655b87b..7fcaa5acf6 100644
--- a/app/test-dma-perf/main.c

*eal_args, char **new_argv)
                        i++;
                        continue;
                }
-               strlcpy(new_argv[new_argc], argv[i], 
sizeof(new_argv[new_argc]));
+               strlcpy(new_argv[new_argc], argv[i], MAX_EAL_PARAM_LEN);
                new_argc++;
        }

Thanks,
Anoob
