[Click] LinearIPLookup: multiple routes for the same prefix?

[Eddie Kohler]

Hi all,

Does anyone rely on this LinearIPLookup behavior?

"Two or more route arguments may refer to the same address prefix. The
last-specified route takes precedence. However, the earlier-specified routes
remain in the table; if the last-specified route is deleted, an
earlier-specified route will take over."

The other routing table elements do not support these semantics, so I'd like to 
remove them.
