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

Hi all: This series is an update version (hope the final version) of multiqueue (VIRTIO_NET_F_MQ) support in virtio-net driver. All previous comments were addressed, the work were based on Krishna Kumar's work to let virtio-net use multiple rx/tx queues to do the packets reception and transmission. Performance test show the aggregate latency were increased greately but may get some regression

virtio_net paravirtualized driver does not have a tx_timeout() function to guarantee that the driver will recover properly after receiving a timeout during a transmission of a packet. This patch add this feature and throw a timeout exception after 5 HZ. Considering some tests, this is the best time to use here. Signed-off-by: Julio Faracco <jcfaracco at gmail.com> Cc: Jason Wang

When initializing XDP in virtnet_open(), some rq xdp initialization may hit an error causing net device open failed. However, previous rqs have already initialized XDP and enabled NAPI, which is not the expected behavior. Need to roll back the previous rq initialization to avoid leaks in error unwinding of init code. Also extract helper functions of disable and enable queue pairs. Use newly

Hi, This two small patches improves ndo_close() callback to follow the mirror sequence of ndo_open() callback. This improves the code auditing and also ensure that xdp rxq info is not unregistered while NAPI on RXQ is ongoing. Please review. Patch summary: patch-1 ensures that xdp rq info is unregistered after rq napi is disabled patch-2 keeps the mirror sequence for close() be mirror of open()
