Ok, please see RFC 3697 for the latest document on the flow label. This reflects current concensus.

Perhaps this happens because RFC 2402 says that the IPv6 flow label is mutable (in para. 3.3.3.1.2.1). But RFC 2460 seems to disagree in terms of current use (as of 1998), in Appendix A, even though in Section 6 the words allow for any sort of change in the future use of this field ("subject to change"). However, if this flow label is to be included in the ICV, as long as the flow label is returned to its original value before header verification at the destination side (be it tunnel or transport mode), all should be fine. Unless the wg has resolved that the flow label is absolutely *not* still "subject to change," what's the urgency to get it included in the ICV? Are we lacking for fields included in the ICV? Do we just need words to justify its non-inclusion?
