b4860qds shared mac USDPAA can not recieve replay pkts from dpdk pktgen with FD Status 0x00000020

[BinLiu1]

Hi,

On b4860qds board, I configure 1G SFP Port as a shared-mac and use config.xml as well as policy.xml to split the traffic according to the following rules:

1)  Udp pkt with dst port 2152 goes to USDPAA

2) Otherwise goes to kernel

And then run the example case: reflector using the command:

reflector -d 0x10000000 -b 1600:1600:1600 -c config.xml -p usdpaa_policy_hash_shared_mac_ipv4_nodefault.xml

root@b4860qds:/apps/usdpaa_example# ./reflector -d 0x10000000 -b 1600:1600:1600 -c config.xml -p usdpaa_policy_hash_shared_mac_ipv4_nodefault.xml

Then I use dpdk pktgen to replay the udp pkts with dst port 2152 to test line rate, but no pkt recieved  by  USDPAA and A lot of errs in dmesg log

And a lot of rx errors rasied!!

what does this mean? Please help me. Thanks a lot!

The pkts I reply and policy file are shown in the attachments

I did this as 9.9.13.1.6 told to , The only difference is I did it with reflector example.

I think reflector can support shared MAC interface. Why did it report FD status = 0x00000020? Which step I missed?

Do you know what does FD status = 0x00000020 mean? 

Thanks.
