   The following changes are performed:
   
    o Documentation/Configure.help
      net/Config.in
           Configure option and help text for the new feature.

No config option please.  If device driver indicates it wants this
behavior with a flag bit, no need to duplicate this logic.
It is likely that it will not be just z-series machines that
will find this useful.
