DPDK has an XDP driver too so you can use that and also work with network cards that do not support XDP or the zero copy variant for more flexibility. Though DPDK can be a pain in and of itself, it is fairly opinionated and I don't like all of its opinions. It has its roots in switching and routing applications and using it for an endpoint can have some mismatches in opinion. It is open source so you can modify it which works out for me in the end.
