Do not report RTM_MISS up on IP encapsulation implicit lookups. This should
fix RARP as well as improving performance. Chances are that it will fix
an error having to do with renumbering net interfaces too. Thanks to
Angelos and Theo for help with the fix, and Martin and Phil for reassuring
it was a general bug.
