Hello Rami,

yes the devices are bound using the igb_uio. I cannot use
uio_pci_generic, as the X710 is not supported in these drivers.

> [root@dhcp13-55 pain]# lib/dpdk/dpdk-17.05.1/usertools/dpdk-devbind.py -b uio_pci_generic 0000:04:00.0
> Error: bind failed for 0000:04:00.0 - Cannot bind to driver uio_pci_generic

This is listed in known issues:
