  Log:
  Revert nd6.c revs. 1.67, 1.68, 1.69, 1.70 in an attempt to unbreak
  IPv6 over point-to-point gif(4) tunnels.
  
  These revisions caused a host route to the destination of a
  point-to-point gif(4) interface to not get installed when the interface
  and destination addresses were assigned.  This caused
  "no route to host" errors when trying to send traffic over the
  interface.  The first packet arriving inbound over the tunnel,
  however, would cause the correct route to get installed, allowing
  subsequent outbound traffic to be routed correctly.
  
  gif(4) interfaces with prefix lengths of less than 128 bits
  (i.e. no explicit destination address assigned) were not affected
  by this bug.
  
  This bug fix is a possible candidate for a 6.2-RELEASE errata note.
