drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packets

Browse source

commit 5188cd44c5 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).
