I think so. Check bin/3477 which I sent. It will match your request.
I tried to "snoop" only with (modified)tcpdump. But you needs to
disable IP stack(don't set any address to interfaces including lo0),
as you said.
About network interfaces, I want some filtering for IP stack. In
current implementation, Incoming packet is checked for all addrsses of
all interfaces. I want to accept some addresses for one interface and
other addresses for another.
If this is implemented, I can snoop one network on host connected to
other network using IP.
