Is that true? This is what i did ifdown eth1 (Interface has IP a.b.c.d) dpdk-devbind.py --bind=3Digb_uio eth1 At this point I can no longer manage the interface via ifconfig which is un= derstandable.When i ran the ethtool app and did a portstats I can see the c= ount increase but am not sure if its the actual data being forwarded to tha= t IP or some arp request.
