The data packets are not forwarded by PIM-SM, but by the kernel.
I am excluding the data packets encapsulated in PIM Registers,
because those are not used in Bidir-PIM.
PIM-SM however installs (via the MFEA) the forwarding entries in the
kernel.

If you are interested in the PIM control packets however, then
PimNode::proto_recv() inside pim/pim_node.cc is the entry point, and
then follow the code :)
