Hi,

If you want to use igb_uio instead of vfio-pci, then you have to make the
following changes in the GRUB
GRUB_CMDLINE_LINUX="iommu=pt, intel_iommu=on"

update grub settings and reboot the machine.

When we are running DPDK on virtual functions, then it is recommended to
use vfio-pci instead of igb_uio.
You can refer this link
http://mails.dpdk.org/archives/dev/2014-August/004610.html for more details.

Regards
Dheeraj Dang
