[Click] Fwd: user level vs kernel level

[Harald Schioeberg]

Hi, 

from the doc of FastUDPSource: 

"FastUDPSource is a benchmark tool [..] Each time the FastUDPSource
element is called, it increments the reference count on the skbuff
created and returns the skbuff object w/o copying or cloning [..] "

This thing explicitly uses kernel-only features (e.g. direct access to
skbuff), that's why the element is unavailable in userspace ...
