Stefano Brivio 16b08367a5 tap: Fill the IPv6 flow label field to represent flow association
This isn't optional: TCP streams must carry a unique, hard-to-guess,
non-zero label for each direction. Linux, probably among others,
will otherwise refuse to associate packets in a given stream to the
same connection.
