[PATCH net-next v1 0/5] virtio: support packed ring
Hello everyone,
This patch set implements packed ring support in virtio driver.
Some functional tests have been done with Jason's
packed ring implementation in vhost:
https://lkml.org/lkml/2018/7/3/33
Both of ping and netperf worked as expected.
RFC (v6) -> v1:
- Avoid extra virtio_wmb() in virtqueue_enable_cb_delayed_packed()
when event idx is off (Jason);
- Fix bufs calculation in
