There is a build time configuration option, CONFIG_RTE_LOG_LEVEL, it
became default to RTE_LOG_INFO recently, please update it to
RTE_LOG_DEBUG to get debug messages.

With optimization enabled, CONFIG_RTE_LOG_LEVEL causes log code lower
than defined value optimized out, so setting runtime log level lower
than CONFIG_RTE_LOG_LEVEL doesn't work.
