[PATCH RFC v5 net-next 0/6] enable tx interrupts for virtio-net
Hi:
This is a new version of trying to enable tx interrupts for
virtio-net.
We used to try to avoid tx interrupts and orphan packets before
transmission for virtio-net. This breaks socket accounting and can
lead serveral other side effects e.g:
- Several other functions which depends on socket accounting can not
work correctly (e.g TCP Small Queue)
- No tx completion which make BQL or

[PATCH RFC v4 net-next 0/5] virtio_net: enabling tx interrupts
Hello:
We used to orphan packets before transmission for virtio-net. This breaks
socket accounting and can lead serveral functions won't work, e.g:
- Byte Queue Limit depends on tx completion nofication to work.
- Packet Generator depends on tx completion nofication for the last
transmitted packet to complete.
- TCP Small Queue depends on proper accounting of sk_wmem_alloc to work.
