Thanks Raju..

These SR-IOV interfaces are reachable with linux drivers and also i have
verified with dpdk 2.2.0, which is running without any issues.
But when i bring in dpdk17.05, it failed to come up with above mentioned
error messages.

please help me if, is it known issue with new SR-IOV drivers? or did i miss
something?
