TURN-08 will say that a server should copy the flow label, and if this
cannot be done, then treat the packets to/from each peer as a separate
flow with separate labels. This is all part of the new concept of a
Preserving allocation (what I called a "Fully-Compliant allocation" in
Philly) that I am in the process of adding right now.

I myself am not sure what the "proper" handling of the flow infos is. If anyone knows, that would be some 6man and/or v6ops people (not including me). Flow infos is not just like DSCP. Reflecting this, the Linux(-specific) API for flow infos is completely different from that of DSCP and TTL...

Pending any approved use of flow labels, there is IMU only one consistent behavior, everywhere: the flow label field MUST be ignored when received, and MUST be set to 0 when created .

If and when some use is approved, it will be time to decide whether, in TURN in particular, another behavior is more appropriate.
