Hi Yingzhi,

PMD_RX_LOG is defined in ixgbe_logs.h (see code snippet below).=20
=09
	#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 d=
efined. Just recompile DPDK with 'CONFIG_RTE_LIBRTE_IXGBE_DEBUG_RX=3Dy' to =
resolve your issue.

Thanks,
Mark
