[dpdk-dev] Debugging igbvf_pmd

[Sambath Kumar Balasubramanian]

Sorry pressed the send button too soon. The NIC Card we are using is

Intel Corporation 82576 Virtual Function (rev 01)

Do we need to do now NIC/CPU low level debugging or is there some issue in
the sw that could cause the packet to be dropped below this log message.

PMD: eth_igb_xmit_pkts(): port_id=3 queue_id=0 pktlen=60 tx_first=14
tx_last=14

PMD: eth_igb_xmit_pkts(): port_id=3 queue_id=0 tx_tail=15 nb_tx=1

Thanks,
Sambath
