How can I test this? I tested on RELENG_6 machine which has following hooks:
ngctl mkpeer xl1: tee lower right
ngctl connect xl1: xl1:lower upper left
ngctl name xl1:lower xl1_tee
ngctl mkpeer xl1_tee: netflow left2right iface0
ngctl name xl1:lower.left2right netflow
ngctl connect xl1_tee: netflow: right2left iface1
ngctl msg netflow: setifindex { iface=0 index=2 }
ngctl msg netflow: setifindex { iface=1 index=1 }
ngctl mkpeer netflow: ksocket export inet/dgram/udp
ngctl msg netflow:export connect inet/127.0.0.1:8818
ngctl mkpeer xl0: tee lower right
ngctl connect xl0: xl0:lower upper left
ngctl name xl0:lower xl0_tee
ngctl mkpeer xl0_tee: netflow left2right iface2
ngctl name xl0:lower.left2right netflow0
ngctl msg netflow0: setifindex { iface=2 index=4 }
ngctl connect xl0_tee: netflow0: right2left iface3
ngctl msg netflow0: setifindex { iface=3 index=3 }
ngctl mkpeer netflow0: ksocket export inet/dgram/udp
ngctl msg netflow0:export connect inet/127.0.0.1:8818
It seems like works at a first glance.

I see. How can I make system to send unexpected messages to ngctl?
