[PATCH 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!
