[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.
