Overview:
I have created an application based on =E2=80=9Cexamples/l2fwd=E2=80=9D.
There is a problem that unable to transmit any packets.
(Receiving packets is working)

It seems similar to the following bug:
https://bugs.dpdk.org/show_bug.cgi?id=3D590

Steps to Reproduce:
1. Create SR-IOV VF on Hypervisor
2. Create VM with SR-IOV-Passthrough=20
3. Bind "igb_uio" to VF
4. Launch software

At step2, VF can communicate a external switch

Actual Results:
No packets are transmitted.

When "rte_eth_stats_get" is executed,
=E2=80=9Coerrors=E2=80=9D matched the number of packets that were attempted=
 to be sent.

Expected Results:
The packets should be transmitted.
