[PATCH net-next 3/3] virtio-net: clean tx descriptors from rx napi

2017-04-02 Thread Willem de Bruijn
From: Willem de Bruijn Amortize the cost of virtual interrupts by doing both rx and tx work on reception of a receive interrupt if tx napi is enabled. With VIRTIO_F_EVENT_IDX, this suppresses most explicit tx completion interrupts for bidirectional workloads. Signed-off-by: Willem de Bruijn ---
