Do you mean changing this line?
    /* default value from build option */
    internal_cfg->log_level = RTE_LOG_LEVEL;
It means using the most verbose level available in the build.

Maybe we should set RTE_LOG_NOTICE or RTE_LOG_WARNING,
However, there is already --log-level for the user and rte_set_log_level()
for the application developper.
So this default log level is only used for DPDK trials and development.
Probably that being verbose is a good option for such cases?
