Problem I am facing is that ping fails because ARP replies are not received by the DPDK device. I am seeing that ARP request is received by the receiving host and it is even sending a ARP reply but this is not received on DPDK port. I ensured that I set correct RSS value (as in L3FWD app) and changed initialization procedure and removed any modification of packet. My set up is as shown below : HostA(172.16.16.101) <--> (Port0) DPDK Device (Port1) <--> HostB(172.16.16.102). I am able to get default L2fwd app after removing packet modification and testpmd with multiple RX/TX queue to work on this device successfully. OS : Ubuntu 12.04 Processor : ATOM Board : Intel I354 Command used : ./l2fwd -c 7f -n 4 -- -p 3 -config=(0,0,1),(0,1,2),(0,2,3),(1,0,4),(1,1,5),(1,2,6) DPDK Version : 1.6.0 and 1.7.0 (I have tried both) I have even enable debug messages on PMD and see that no reply packets were receive on Port1. Can anybody please help to fix this issue. Kindly let me know if you need any information. Thanks and Regards, Tilak
