Hi, I have been trying to use VPP with the mlx4 pmd. However, VPP is not processing any packets. My current setup includes two machines that are directly connected. One machine is running VPP with the mlx4 pmd. The other machine is using the Linux kernel for networking. I assigned an ip address (10.0.1.1/24) to the VPP interface and brought the interface up. I assigned (10.0.1.2/24) to the interface on the other machine and brought it up. Pinging the VPP interface from the other machine is unsuccessful. Also, the 'show int' command displays 'dpdk tx failure' after pinging from VPP. I was able to verify with a debugger that the RX queues are being polled, but there are no packets available to process. I enabled tracing on the dpdk input node, but no packets end up being traced. I'm not sure if this is just a configuration issue or some other problem.
Here is the VPP and DPDK versions I am currently using. Any help will be greatly appreciated.
