similar to: [PATCH net-next v3 0/3] Multiqueue support in virtio-net

Hi all: This series is an update version of multiqueue virtio-net driver based on Krishna Kumar's work to let virtio-net use multiple rx/tx queues to do the packets reception and transmission. Please review and comments. A protype implementation of qemu-kvm support could by found in git://github.com/jasowang/qemu-kvm-mq.git. To start a guest with two queues, you could specify the queues

As multi-queue nics were commonly used for high-end servers, current single queue based tap can not satisfy the requirement of scaling guest network performance as the numbers of vcpus increase. So the following series implements multiple queue support in tun/tap. In order to take advantages of this, a multi-queue capable driver and qemu were also needed. I just rebase the latest version of

This patch series resurrects the earlier multiple TX/RX queues functionality for virtio_net, and addresses the issues pointed out. It also includes an API to share irq's, f.e. amongst the TX vqs. I plan to run TCP/UDP STREAM and RR tests for local->host and local->remote, and send the results in the next couple of days. patch #1: Introduce VIRTIO_NET_F_MULTIQUEUE patch #2: Move

From: Willem de Bruijn <willemb at google.com> Add napi for virtio-net transmit completion processing. Based on previous patchsets by Jason Wang: [RFC V7 PATCH 0/7] enable tx interrupts for virtio-net http://lkml.iu.edu/hypermail/linux/kernel/1505.3/00245.html Changes: RFC -> v1: - dropped vhost interrupt moderation patch: not needed and likely expensive at light

On newer hosts that support delayed tx interrupts, we probably don't have much to gain from orphaning packets early. Based on patch by Jason Wang. Note: this will likely degrade performance for hosts without event idx support. Various fallback options are available, including orphaning conditionally. Testing TBD. Signed-off-by: Michael S.
