It means that your module is doing SOMETHING
I can not say if it is working as I don't know aything about your node..
I presume it is based on the 'tee' node..

no,  you only connected to the 'upper' part of the ethernet 
interface so you are only capturing outgoing packets
I'm not sure if the node correctly does not could bytes going out a
disconnected hook or not.


you should also do: ngctl connect ng_m: ed0: left lower

or something like that I presume

you may also want to look at the ng_etf node
(and it's man page (man ng_etf)


I'm presuming youhave read the man pages.. there should be one for every
node type..
ng_tee ng_ether etc.

look at the packets by attaching nghook to the left2right and 
right2left hooks
