No harm taken, kernel bypass technologies have moved fast in the last decade. As a side note though, I would encourage you to revisit DPDK. I've worked in the low latency space for a long time, and used pretty much every solution out there, open source or proprietary, and DPDK is one of my favorite. This is because DPDK is not _just_ poll mode drivers, it's a a full featured SDK for low latency packet processing. You get top notch thread safe memory pools to store packets, thread safe queues, hand written intrinsics optimized hashing and CRC algos, a cooperative scheduler in case you isolate your CPUs, etc, etc.
