That would be similar to what I'm doing, but I'm not really trying
to tunnel anything. I am trying to duplicate the behaviour of two
ethernet interfaces connected by an external cross-over cable, and I'm
trying to duplicate it at the network-device interface level so that
common tools (and my own tools) can treat these virtual interfaces
just like ethernet interfaces.
Oh ok, what you seem to want is some kind of "Ethernet loopback++", but
the "looped" packets should come back from a virtual interface instead
of the same interface?
Yes. In practice, I use a pair of virtual interfaces, so I send on one
virtual and receive on the other. I use separate software to bridge,
or the normal linux stacks to route, the packets to other interfaces,
including real interfaces.
Btw, does the kernel support traditional loopback, so that at the last
stage, just before sending a packet on the wire, it would be pushed back.
Not that I'm aware of.
