Hi Yingzhi,

PMD_RX_LOG is defined in ixgbe_logs.h (see code snippet below). 

        #ifdef RTE_LIBRTE_IXGBE_DEBUG_RX
        #define PMD_RX_LOG(level, fmt, args...) \
        RTE_LOG(level, PMD, "%s(): " fmt "\n", __func__, ## args)
        #else
        #define PMD_RX_LOG(level, fmt, args...) do { } while(0)
        #endif

As you can see, the logs are only printed if RTE_LIBRTE_IXGBE_DEBUG_RX is 
defined. Just recompile DPDK with 'CONFIG_RTE_LIBRTE_IXGBE_DEBUG_RX=y' to 
resolve your issue.

Thanks,
Mark
