Hi Sambath,

Did you follow the step of applying the mac to each of the virtual function as per the release notes in DPDK ?
And ofcourse the src mac of your packets should be 'that' mac as set above.

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
