This is not really defined yet. There are some expired drafts with incomplete
ideas, and there is a current draft in the IPv6 WG that aims to clarify
the basic definition of the flow label. Although I'm an author of that
draft, I still have some problems with it myself. However, it's at
http://www.ietf.org/internet-drafts/draft-ietf-ipv6-flow-label-01.txt

There is also an individual submission
http://www.ietf.org/internet-drafts/draft-banerjee-flowlabel-ipv6-qos-03.txt
but this has no official status.

At the moment the flow label is of no use for diffserv. If we do clarify the
formal definition, it could possibly be used as a field in an MF classifier.
