[PATCH 00/10] Split UFO into v4 and v6 versions.
UFO support in the kernel applies to both IPv4 and IPv6 protocols with the same device feature. However some devices may not be able to support one of the offloads. For this we split the UFO offload feature into 2 pieces. NETIF_F_UFO now controlls the IPv4 part and this series introduces NETIF_F_UFO6. As a result of this work, we can now re-enable NETIF_F_UFO on virtio_net devices and restore
