...atomicy of read and ack in guest otherwise we may ack more times than being notified. This is done through handling the whole config change interrupt in an non-reentrant workqueue. Signed-off-by: Jason Wang <jasowang at redhat.com> --- Changes from v6: - move the whole event processing to system_nrt_wq - introduce the config_enable and config_lock to synchronize with dev removing and pm - protect the ack with rtnl_lock Changes from v5: - notify the chain before acking the link annoucement - ack the link announcement notification through control vq Changes from v4: - typos - handle workqueue unc...

Hello 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. Test Environment: - Intel(R) Xeon(R) CPU E5620 @ 2.40GHz, 8 cores 2 numa nodes - Two directed connected 82599 Test Summary: - Highlights: huge improvements on TCP_RR
