veth are software interfaces, meaning there is no real NIC behind. That's why you cannot bind them to igb_uio. You can use KNI interfaces for communicating a DPDK application with the kernel interfaces and viceversa. There is an overhead on doing so, but whether this is an appropriate solution or not, depends on your use case. What do you plan to do? Marc > > > Regards, > Sachin.
