  52  * Internet and OSI related options as part of inclusion of <xti.h>
  53  *
  54  * Also XTI specification intrudes on <netinet/in.h> TCP_ and IP_ namespaces
  55  * and sometimes redefines the semantics or types of some options with a
  56  * different history in that namespace. The name and binary value are exposed
  57  * but option semantics may be different from what is in XTI spec and we defer
  58  * to the <netinet/in.h> precedent.
  59  *
  60  * New applications should not use these constants. These are meant
  61  * for compatibility with older applications.
