<div class='commit-subject'>virtio_net: exploit napi_complete_done() return value</div><div class='commit-msg'>Since commit 364b6055738b ("net: busy-poll: return busypolling status to
drivers"), napi_complete_done() returns a boolean that can be used
by drivers to conditionally rearm interrupts.
This patch changes virtio_net to use this boolean to avoid a bit of
overhead for busy-poll users.
Jason reports about 1.1% improvement for 1 byte TCP_RR (burst 100).
