Hi,
This patch series mainly includes 3 new features for AF_XDP pmd. 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].
