    "content": "Hi,\n\nThis 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 is in \nRFC stage [1].\n\n[1] https://www.spinics.net/lists/netdev/msg568337.html \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: add busy poll support\n\n doc/guides/nics/af_xdp.rst          |   5 +-\n drivers/net/af_xdp/rte_eth_af_xdp.c | 210 +++++++++++++++++++++-------\n 2 files changed, 160 insertions(+), 55 deletions(-)"
