By looking at the eth_pcap_tx(pkts, nb_pkts) function, I think it may not work properly. I think it should return nb_pkts instead of num_tx. Indeed, if pcap_sendpacket() fails -- I don't know in which case it can occur -- the function will return a number lower than nb_pkts, causing a caller like l2fwd_send_burst() to free some mbufs. But all mbufs are already freed by eth_pcap_tx(). I don't know if it's related to your problem but it may help. Regards, Olivier
