Though this doesn't cause any functional issue but it is needed for the consumers of "ltr_ignore" as the index printing for "ltr_show" is missing. For example, w/o this change, a user that wants to ignore LTR from ME would do something like echo 5 > ltr_ignore but the index for ME is 6. Printing a reserved IP helps to properly calculate LTR ignore offsets. Cc: "David E.
