[PATCH net-next 2/3] virtio-net: transmit napi

2017-04-02 Thread Willem de Bruijn
From: Willem de Bruijn Convert virtio-net to a standard napi tx completion path. This enables better TCP pacing using TCP small queues and increases single stream throughput. The virtio-net driver currently cleans tx descriptors on transmission of new packets in ndo_start_xmit. Latency depends o
