I want to read from pcap file and send to network interface like tcpreplay.

So I run

> testpmd -c f --vdev "eth_pcap0,rx_pcap=a.pcap,tx_iface=eth0" --

but the statistics shows a lot of drop

port 0 : RX-packets : 479122

port 1 : TX-packets : 371441     TX-dropped: 107681

Why is that? What am I doing wrong?

My env is dpdk-2.2.0, Ubuntu 14.04, X710-DA2.
