Hi, I upgraded from 2.2.0 to 17.02.1 using the i40e driver, and I'm seeing very weird behavior that's easily reproducible. My receiving thread/lcore calls rte_eth_rx_burst(), changes the endianess on some of the packet headers, and puts the pktmbuf onto a ring for the next eal thread to process and eventually free. After upgrading, I'm seeing that when rte_eth_rx_burst starts reusing buffers from the mempool, it's returning buffers that don't have the new packet's data, but rather the old data where I had already changed the endianess on some of the headers. I removed the ring part, and even doing:
1) rte_eth_rx_burst 2) Change endianness 3) free pktmbuf all within the same thread causes this issue to happen too. I've looked through the changelog and don't see anything obvious that would be causing this. Has anyone seen this happen? Thanks
