Hi Rami,

Thanks for your reply.
yes. i already did the binding and here is the output.
[root@localhost dpdk-stable-17.11.1]# ./usertools/dpdk-devbind.py -s

Network devices using DPDK-compatible driver
============================================
0000:03:00.0 'Ethernet Server Bypass Adapter 155d' drv=vfio-pci unused=
0000:03:00.1 'Ethernet Server Bypass Adapter 155d' drv=vfio-pci unused=
0000:05:00.0 'Ethernet Server Bypass Adapter 155d' drv=vfio-pci unused=

Network devices using kernel driver
===================================
0000:01:00.0 'I350 Gigabit Network Connection 1521' if=enp1s0f0 drv=igb
unused=vfio-pci *Active*
0000:01:00.1 'I350 Gigabit Network Connection 1521' if=enp1s0f1 drv=igb
unused=vfio-pci
0000:01:00.2 'I350 Gigabit Network Connection 1521' if=enp1s0f2 drv=igb
unused=vfio-pci
0000:01:00.3 'I350 Gigabit Network Connection 1521' if=enp1s0f3 drv=igb
unused=vfio-pci

Other Network devices
=====================
<none>

similarly tried with igb_uio as well, but i see the same result ( "EAL: No
probed ethernet devices" )

Thanks,
Venkat
