Can you elaborate a bit more on the patch contents? I'm not entirely sure
what it does and furthermore flow-tools source code does not contain any
references to the CMSG_XXX macros, so it is effectively a no-op for
net/flow-tools. It might work for flow-tools-ng though.
It'd be helpful to have a small description of what these changes does,
so it will be possible to elaborate the same fix for net/flow-tools.
