I'm puzzled at the lack of a substantive description of this bug. There is no detail, no steps to reproduce, not even any anecdotes except a handful contributed in the comments.

For example, does this affect native IPv6 connections only? Tunneled connections such as 6rd or 6in4 use IPv4 for ingress and egress, but then are routed internally to the destination LAN subnet as v6, so I'm guessing that the v6 flow tables, and therefore this bug, would be in effect.  But that is just a guess; as this is in general release, it would be helpful to know whether mitigation is needed without doing a bunch of ad-hoc, nearly-uninformed testing.
