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

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.
