Tunnel mode you mean, i think.

IPsec is slightly different since i need to use state in the core. i.e
it is stateful. Nothing that pktgen does today has such requirements.

Thats one idea i havent thought of.
i.e the code would look like:
-----
if (mode == tunnel)
err = mytunneloutput (x, skb);
else
err = x->mode->output(x, skb);
if (err)
goto error;
err = x->type->output(x, skb);

This is what you are suggesting?
I am probably better off going back to creating a dummy dst with just
those two fields when in tunnel mode;->
