====================
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
====================
