   Many thanks - so, it compiles on a one month old -CURRENT, but it
   fails when i try to use it on a loopback interface - i'm able to wrap
   a real one though:

mkpeer ifwrap qq upper
name .:qq wrap_disc0
disconnect .:qq
msg wrap_disc0: attach "disc0"
ngctl: send msg: Operation not supported

   Anyway, do others see an interest in it ? would it be worth
   integrating it into the tree ? Except for ng_netflow over loopback
   links, would there be other consumers of this feature ?
