Thanks for the information,
however, although converters can't have the same type, it seems that
they still can receive the same packet.
the ip_en converter and the ppp_en converter are different, but their
bottem type are the same.
(especially when both them register the pattern of received packet
if there are (ip_en converter) and (ip_ppp converter + ppp producer
+ ppp_en converter) on the same computer.
The ip producer transmits a packet down, then which path will be selected?
I'm just confused by these kind of conditions. What principle does io-net

Can I assign it when I load/register the module?

You can't have two converters of the same (ie en->ip) at the same time.
You could have two converters, like en->ip and en->xyz. In that case,
net would give the packet from the en producer to the filter which
the en type it wants (which I suppose could be all packets).
