Subject: [PATCH 1/2] arping: Fix finding of a default interface when no -I is
specified.
By default, no interface string should be supplied. This ensures that we can
recognize if an interface was specified or omitted. Previously, when -I was not
used, default interface string was compiled-in and the automatic selection
didn't work correctly.
