 On application startup, there is a lot of EAL information printed. Is there any way to reduce this?
 ---------------------------------------------------------------------------------------------------
 
-Yes, each EAL has a configuration file that is located in the /config directory. Within each configuration file, you will find CONFIG_RTE_LOG_LEVEL=8.
-You can change this to a lower value, such as 6 to reduce this printout of debug information. The following is a list of LOG levels that can be found in the rte_log.h file.
-You must remove, then rebuild, the EAL directory for the change to become effective as the configuration file creates the rte_config.h file in the EAL directory.
