 "Device is busy" error probably means that ng_l2tp node is still used in 
 netgraph. You can check it with 'ngctl list' command. You can't unload 
 module while it is used.
 
 IMO this is not ng_l2tp but sl2tps problem. I would recommend you 
 net/mpd4 port, present 4.2.2 version supports L2TP much better and 
 stable then sl2tps.
