[ovs-discuss] Fwd: ovs-dpdk could not process 80 bytes packet size at 1G speed

Hi

I have the development version of ovs-dpdk installed in my system.

I am trying to send 80 bytes packet size at 1G speed(~1250000)

But i found that there is nearly 20% to 50% of packet loss at the
reception(ovs-dpdk) end.

I am getting the error message as "APP: send_burst: Attempted to enqueue
32 mbufs to vhost port port4, but only 0 succeeded". Its like the
packets in buffer are not transmitted completely. I tried changing
BURST_TX_RETRIES value from 16 to 64. But still there is some packet loss.

When i send some erroneous packet of the same size and speed , then the
statistics shows the exact 1250000 rx_errors packets


Could you please let me know what else i am missing? What i should do to
fix this issue?

Listed the complete error message below
