OpenBSD/src m6x8fRKsys/netinet6 ip6_forward.c

   Do not assume if_get(9) returns a non NULL ifp when using a route
   interface index.

   This assumption is true for the moment iff the route lookup *and* the
   if_get() are done under KERNEL_LOCK().  This is not the case here.

   Found the hardway by Hrvoje Popovski.
