How can packet flow be traced on DPDK? W= here are all the logs stored if we do enable the _DEBUG configs in config/ = directory?

Thanks!! Hi, I am observing that the SR-IOV enabled NIC does not increment any VF packet= counters despite incoming packet flow. I have enabled some debug logs like= CONFIG_RTE_LIBRTE_IXGBE_DEBUG_RX in config file. Can someone point me to where these logs are being printed so I can try to = figure out where packets are being dropped? Or how can I debug DPDK packet = flow related issues (are there any stats I can look at)? Thanks Anjali
