But the only way to preserve the meaning - the fact that the combination
of source address and flow label uniquely identifies the flow because the
source host guarantees that each flow has a unique label - would be to
restore the value to the orginal value previous to any munging/tunelling
in the middle.   If you alter the value, where do you store the original 
value?
