Yes I think we have faced the same problem,communication with RPL
supporting devices was failing otherwise.Your patch is also more
complete since it also implements #ifdef .About the comment,yes I have
run checkpatch twice with no errors,but ok :)

Hi all!
I have added a dump function(always return true) to recognise RPL
extension
header(RFC6553)
Otherwise packet was dropped by kernel resulting in failing
communication in
RPL DAG's between
linux running border routers and devices in the graph.For example
communication
with contiki OS running devices was previously impossible.
