drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packets
commit 5188cd44c55db3e92cd9e77a40b5baa7ed4340f7 upstream.
UFO is now disabled on all drivers that work with virtio net headers,
but userland may try to send UFO/IPv6 packets anyway. Instead of
sending with ID=0, we should select identifiers on their behalf (as we
used to).
