> Hi,
> The l2fwd sample application in my environment does not send packets

> Environment:
> Host OS: ubuntu 14.04 x86_64
> NIC: intel x540-t1
> Guest OS: ubuntu 14.04 x86_64
> DPDK: v1.7.0
> Some findings:

> Anyone know the issue and the corresponding fix? Thanks.

One thing that is worth checking is that the source mac address of the packets being sent matches that of the VF interface, as the packets can't be sent otherwise.
