I wanted to replace debugfs with netlink which I did. The feature what you are looking for is now upstream in a new driver named "mac802154_hwsim" - you need a recent kernel... Having two nodes connected to each other fakelb is enough. The new driver allows you to run a individual mesh network with 1000 nodes connected RIOT/Contiki/Linux/openthread/etc.... you need just enough memory to run it. And I think with 1000 nodes it will run terrible slow, because each userspace stack need to filter it _in_ userspace.

You need to apply these patches and then run a recent kernel. Then load mac802154_hwsim and using the tool which is more self explained. Sorry I don't have any example currently how to set it up... but you should try fakelb with 3 nodes, every phy is monitor. Then on two monitors each running openthread. One monitor runs wireshark/tshark, Then you should able too see the traffic between the nodes. - Alex [0] https://www.spinics.net/lists/linux-wpan/msg05122.html
