I have test the VFIO driver and IGB_UIO driver by l2fwd for many times. I find
that the VFIO driver?s performance is not better than the IGB_UIO.
Is something wrong with my test? My test is as follow:
1. bind two 82599 ether to VFIO ./tools/dpdk_nic_bind.py -b vfio-pci

It is a Westmere if I am correct. So,use UIO.

My experience is that the CPU isn't as an important part of the platform
as the chipset. IOW, VFIO requires full IOMMU isolation
