[v2,0/3] add more features for AF_XDP pmd

  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].

V2 changes:

1. improve mutli-queue support by getting the ethtool channel, so the
   driver is able to get a reason maximum queue number.
2. add a tiny cleanup patch to get rid of unused struct member
3. remove the busy-poll patch as its kernel counterpart changes, will
   update the patch later

Xiaolong Ye (3):
  net/af_xdp: enable zero copy by extbuf
  net/af_xdp: add multi-queue support
  net/af_xdp: remove unused struct member
