Bug ID: 924
Summary: Mellanox ConnectX6 DPDK dpdk-testpmd Receive error len
error checksum UDP packet performance is very low!
Product: DPDK
Version: 21.11
Hardware: x86

I use Ixia to construct two streams
flow1 udp 64size small packet
flow2 udp 64size small packet error len error checksum
Send per second 30G bps 57 million pps
./dpdk-testpmd -l 4-22 -n 8 -- -i --rxq 19 --txq 19 --nb-cores 18 --rxd 2048

You mention flow2 is with the errors, but also show the performance is good. is this correct?
Do you mean when you have errors you get perf drop?
