[Click] ToHost problem

[Beyers Cronje]

Hi Bart,

It's not necessary to deliver packets to Linux under the userlever
click as Linux already has a copy of the packet. I presume use of
ToHost in userlevel click is provided for configurations where you
want to modify packets before sending them back to Linux.

Kernel module click on the other hand requires use of ToHost for any
packets you want Linux to see/process.

Regards

Beyers
