They are separated independent features, the reason I take them in one patchset is that they have code dependency. 1. zero copy This patch enables `zero copy` between af_xdp umem and mbuf by using external mbuf mechanism. 2. multi-queue With mutli-queue support, one AF_XDP pmd instance can use multi netdev queues. 3. busy-poll With busy-poll, all processing occurs on a single core, performance is better from a per-core perspective. This patch has dependency on busy-poll support in kernel side and now it is in RFC stage [1].
