Hi,
I am using ubuntu 14.04 with intel controller 82574L and I am neither able
to send any packets or receive. My dpdk version is 17.11. However, when I
switched to ubuntu 16.04, it worked with vfio-pci driver. Is something
wrong with 82574L driver in ubuntu 14.04?
Thanks
Avinash Kumar Chaurasia

If it works with vfio-pci driver but not with igb_uio driver, the most
likely cause is that you were trying to run DPDK with IOMMU enabled
(kernel command-line "intel_iommu=on iommu=on"). Switching to iommu=off
or iommu=pt should fix the issue in that case.
