Yes, that's the easiest way to do it with DPDK's mbuf model. Your first approach would work well on frameworks that expose the ringbuffers directly in their API (e.g., netmap). I've implemented it like this in my packet generator MoonGen, you can read Section 4.2. of our paper at https://www.net.in.tum.de/fileadmin/bibtex/publications/papers/MoonGen_IMC2015.pdf for further details.
