[Click] Basic problem of how to transfer packet to kernel under user-level click

[Zhang Shidong]

hello,

On the configuration of Click Router, here is suggestion:

if you are using user level click, thenyou should use:
"toh::Print(toh)->Discard"
 instead of 'toh :: ToHost', which is meant only for kernel click.

My question is: If the Local delivery packet are all Discarded, how can my
linux server receive the packets which destination to  the  local system?

Thanks!
