[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 03/10] ovs: Enable handling of UFO6 packets.
Since UFO6 packets can now be identified by SKB_GSO_UDP6, add proper checks
to handel UFO6 flows.
Legacy applications may still have UFO6 packets identified by SKB_GSO_UDP,
so we need to continue to handle them correclty.

I think there's some misunderstanding here.
I merely mean that after split, host should always have
SKB_GSO_UDP6 set for IPv6.
To make sure legacy userspace/guests don't notice changes,
whenever we detect SKB_GSO_UDP6 we should set VIRTIO_NET_HDR_GSO_UDP,
and whenever we get VIRTIO_NET_HDR_GSO_UDP we should set either
SKB_GSO_UDP6 or SKB_GSO_UDP depending on IP type.
Given this clarification there's...

It seems like it would be cleaner to use the names SKB_GSO_UDPV{4,6},
similarly to SKB_GSO_TCPV{4,6}.
