New Revision: 197203
URL: http://svn.freebsd.org/changeset/base/197203

Log:
  Previously local end of point-to-point interface is not reachable
  within the system that owns the interface. Packets destined to
  the local end point leak to the wire towards the default gateway
  if one exists. This behavior is changed as part of the L2/L3
  rewrite efforts. The local end point is now reachable within the
  system. The inpcb code needs to consider this fact during the
  address selection process.
