    "content": "This patch series mainly includes 3 new features for AF_XDP pmd. They\nare separated independent features, the reason I take them in one\npatchset is that they have code dependency.\n\n1. zero copy\n\nThis patch enables `zero copy` between af_xdp umem and mbuf by using\nexternal mbuf mechanism.\n\n2. multi-queue\n\nWith mutli-queue support, one AF_XDP pmd instance can use multi netdev\nqueues.\n\n3. busy-poll\n\nWith busy-poll, all processing occurs on a single core, performance is\nbetter from a per-core perspective.\n\nThis patch has dependency on busy-poll support in kernel side and now it\nis in\nRFC stage [1].\n\n[1] https://www.spinics.net/lists/netdev/msg568337.html\n\nV2 changes:\n\n1. improve mutli-queue support by getting the ethtool channel, so the\n   driver is able to get a reason maximum queue number.\n2. add a tiny cleanup patch to get rid of unused struct member\n3. remove the busy-poll patch as its kernel counterpart changes, will\n   update the patch later\n\nXiaolong Ye (3):\n  net/af_xdp: enable zero copy by extbuf\n  net/af_xdp: add multi-queue support\n  net/af_xdp: remove unused struct member\n\n doc/guides/nics/af_xdp.rst          |   4 +-\n drivers/net/af_xdp/rte_eth_af_xdp.c | 285 ++++++++++++++++++++--------\n 2 files changed, 213 insertions(+), 76 deletions(-)"
