Using kernel in the name is not very useful, but netlink is the real part that makes sense.

How about one of these:
- DNI = DPDK Netlink Interface
- DNC = DPDK Netlink Control
- NCI = Netlink Control Interface

Being able to control DPDK interfaces via Netlink is one of the customer needs I have heard of late.
