When I send DNS packets, the wireshark simultaneously gets all the packets on two ports. However, using my program with promiscuous mode, one port receives all the packets, but the other port gets nothing. Do you know why it happens? Could it be network topology problem using DPDK, a DPDK design like forwarding mechanism, or just my program bugs? Any comments would be appreciated. Thanks, Daeyoung
