[RFC PATCH net-next 0/6] Always use tx interrupt for virtio-net
According to David, proper accounting and queueing (at all levels, not
just TCP sockets) is more important than trying to skim a bunch of
cycles by avoiding TX interrupts. Having an event to free the SKB is
absolutely essential for the stack to operate correctly.
This series tries to enable tx interrupt for virtio-net. The idea is
simple: enable tx interrupt and schedule a tx napi to free old
