Subject: [PATCH net-next] virtio_net: bulk free tx skbs
Date: Mon, 14 Jan 2019 20:34:26 -0500 [thread overview]
Message-ID: <20190115012847.14730-1-mst@redhat.com> (raw)
Use napi_consume_skb() to get bulk free. Note that napi_consume_skb is
safe to call in a non-napi context as long as the napi_budget flag is
correct.
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

My perf testing setup is down but it works fine on my devel box and
should be fairly uncontroversial.
