[dpdk-dev] Debugging SR-IOV related packet flow problem with DPDK

Hi,

Can someone please help with this? How can packet flow be traced on DPDK? Where are all the logs stored if we do enable the _DEBUG configs in config/ directory?

Pls keep me on cc for response. 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
