    "content": "Async enqueue offloads large copies to DMA devices, and small copies\nare still performed by the CPU. However, it requires users to get\nenqueue completed packets by rte_vhost_poll_enqueue_completed(), even\nif they are completed by the CPU when rte_vhost_submit_enqueue_burst()\nreturns. This design incurs extra overheads of tracking completed\npktmbufs and function calls, thus degrading performance on small packets.\n\nThe first patch cleans up async enqueue code, and the second patch\nenables rte_vhost_submit_enqueue_burst() to return completed packets.\n\nJiayu Hu (2):\n  vhost: cleanup async enqueue\n  vhost: enhance async enqueue for small packets\n\n lib/librte_vhost/rte_vhost_async.h |  24 ++--\n lib/librte_vhost/vhost.c           |  14 +-\n lib/librte_vhost/vhost.h           |   7 +-\n lib/librte_vhost/vhost_user.c      |   7 +-\n lib/librte_vhost/virtio_net.c      | 256 +++++++++++++++++++++----------------\n 5 files changed, 171 insertions(+), 137 deletions(-)",
