Hello!

  I tried to use uio_pci_generic instead of VFIO :

root@devuan4-sysman:~# lsmod | grep uio
uio_pci_generic        16384  0
igb_uio                20480  0
uio                    20480  2 igb_uio,uio_pci_generic
root@devuan4-sysman:~#


root@devuan4-sysman:~# dpdk-devbind.py -s

  Please, help me to resolve this problem.
