RFC 6936, "Applicability Statement for the Use of IPv6 UDP Datagrams with Zero Checksums", April 2013

Section 1.3.5 says:

The ingress of a tunnel seeking to provide good
entropy in the flow label field would therefore need to create a
random flow label value and keep corresponding state so that all
packets that were associated with a flow would be consistently given
the same flow label.  Although possible, this complexity may not be
desirable in a tunnel ingress.

It should say:

The ingress of a tunnel seeking to provide good
entropy in the flow label field would therefore need to create a
pseudo-random flow label value using a stateless method
as described in [RFC6438] so that all
packets that were associated with a flow would be consistently given
the same flow label.

Notes:

It is incorrect that a stateful method is needed, and presumably that
was the complexity judged undesirable. Also, we shouldn't say "random"
when we mean "pseudo-random."
