AVX512 instructions can well handle\nthis kind of data. Packed ring TX datapath can fully transformed into\nvectorized datapath. Rx datapath also can be vectorized by limiated\nfeatures(TSO and mergeable).\n\nMarvin Liu (7):\n  net/virtio: add Rx free threshold setting\n  net/virtio-user: add LRO parameter\n  net/virtio: add vectorized packed ring Rx function\n  net/virtio: reuse packed ring xmit functions\n  net/virtio: add vectorized packed ring Tx function\n  net/virtio: add election for vectorized datapath\n  net/virtio: support meson build\n\n drivers/net/virtio/Makefile                   |  30 +\n drivers/net/virtio/meson.build                |   1 +\n drivers/net/virtio/virtio_ethdev.c            |  35 +-\n drivers/net/virtio/virtio_ethdev.h            |   6 +\n drivers/net/virtio/virtio_pci.h               |   2 +\n drivers/net/virtio/virtio_rxtx.c              | 201 ++----\n drivers/net/virtio/virtio_rxtx_packed_avx.c   | 606 ++++++++++++++++++\n .../net/virtio/virtio_user/virtio_user_dev.c  |   8 +-\n .../net/virtio/virtio_user/virtio_user_dev.h  |   2 +-\n drivers/net/virtio/virtio_user_ethdev.c       |  17 +-\n drivers/net/virtio/virtqueue.h                | 165 ++++-\n 11 files changed, 903 insertions(+), 170 deletions(-)\n create mode 100644 drivers/net/virtio/virtio_rxtx_packed_avx.c"
