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

This attempts to implement a "virtual I/O" layer which should allow common drivers to be efficiently used across most virtual I/O mechanisms. It will no-doubt need further enhancement. The details of probing the device are left to hypervisor-specific code: it simple constructs the "struct virtio_device" and hands it to the probe function (eg. virtnet_probe() or

Curreclty virtion net header is fixed size and adding things to it is rather difficult to do. This series attempt to add the infrastructure as well as some extensions that try to resolve some deficiencies we currently have. First, vnet header only has space for 16 flags. This may not be enough in the future. The extensions will provide space for 32 possbile extension flags and 32 possible
