   It would seem that the flowi structure should use the actual IPv6
   addresses instead of pointers to them, like the IPv4 section does.
   Feedback?

Yes, precisely, thanks for spotting this.  I introduced this
bug when I split out the policy flow cache into a generic spot.

I'll see how much work it is to change all of ipv6 to store
addresses directly into the flowi's instead of via pointers.
