You mean there is not enough log levels? #define RTE_LOG_EMERG 1U /**< System is unusable. */ #define RTE_LOG_ALERT 2U /**< Action must be taken immediately. */ #define RTE_LOG_CRIT 3U /**< Critical conditions. */ #define RTE_LOG_ERR 4U /**< Error conditions. */ #define RTE_LOG_WARNING 5U /**< Warning conditions. */ #define RTE_LOG_NOTICE 6U /**< Normal but significant condition. */ #define RTE_LOG_INFO 7U /**< Informational. */ #define RTE_LOG_DEBUG 8U /**< Debug-level messages. */ Either other "debug" logs can be put as INFO level, or you need a level 9 for verbose debug. But I don't really understand what is the problem of a verbose debug. It is not critical for the acceptance of this patch. Just wanted to discuss it as we have many config options to tune the debug. Please, at least, use the DEBUG word in the option name as done for CONFIG_RTE_LIBRTE_BNX2X_DEBUG_RX.
