Commit 501db511397f ("virtio: don't set VIRTIO_NET_HDR_F_DATA_VALID on xmit") in fact disables VIRTIO_HDR_F_DATA_VALID on receiving path too, fixing this by adding a hint (has_data_valid) and set it only on the receiving path.

Hi, This patches introduce virtio_net_hdr_{from,to}_skb functions for conversion of GSO information between skb and virtio_net_hdr. Mike Rapoport (6): virtio_net: add _UAPI prefix to virtio_net header guards virtio_net: introduce virtio_net_hdr_{from,to}_skb macvtap: use common code for virtio_net_hdr and skb GSO conversion tuntap: use common code for virtio_net_hdr and skb GSO

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
