[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

[PATCH v2 net 0/2] drivers/net,ipv6: Fix IPv6 fragment ID selection for virtio
The virtio net protocol supports UFO but does not provide for passing a fragment ID for fragmentation of IPv6 packets. We used to generate a fragment ID wherever such a packet was fragmented, but currently we always use ID=0! v2: Add blank lines after declarations Ben.
