[dpdk-dev] [PATCH v1 0/3] add more features for AF_XDP pmd

[Xiaolong Ye <xiaolong.ye@intel.com>]

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].
