multiple queue virtio-net: flow steering through host/guest cooperation Hello all: This is a rough series adds the guest/host cooperation of flow steering support based on Krish Kumar's multiple queue virtio-net driver patch 3/3 (http://lwn.net/Articles/467283/). This idea is simple, the backend pass the rxhash to the guest and guest would tell the backend the hash to queue mapping when

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
