I am running a single forwarding program based on dpdk 2.1.0. The program runs on a VM, binding on two interfaces. All it's doing is to forward packets from one interface to another. All ingressing packets are fine but there seems no egressing packets. I used rte_eth_add_tx_callback to register a tx callback. The callback is able to print the right egress packet but the destination is just not receiving it (via tcpdump). Does anybody have the similar experience? Any solution or hints will be great. Thanks, Yiwen
