 For example, if your EAL coremask is 0xff0, the master core will usually be the first core in the coremask (0x10); this is what you have to supply to taskset::

-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.
