[dpdk-users] Fail to build Memnic in Ubuntu 14.04

Dear Matthew,

I think my DPDK works. However, I believe SR-IOV is faster than VirtIO in
VM, so I want to have a try.

Is there any other solution to achieve SR-IOV with DPDK. I am amazing that
MEMNIC is stuck at 2014. Nobody needs that with DPDK in VM?

------------------------------------------------------
./tools/dpdk_nic_bind.py --status

Network devices using DPDK-compatible driver
============================================
0000:00:02.0 'Virtio network device' drv=uio_pci_generic unused=vfio-pci

Network devices using kernel driver
===================================
<none>

Other network devices
=====================
<none>
-------------------------------------------------------
