Would be cool I think, so you could debug vlan code in the kernel using
uml for example.

That is clear.  How to you tell uml_switch which sockets it should
create?

I've looked at it, it doesn't answer the configuration question through.
Your openswan test setup seems to use command mode.  It's not clear
whenever that is the only way to do it.  It shouldn't, for running tests
that likely is perfect, but for other applications I just want a static
configuration and uml_switch shouldn't wait for commands on stdin/out.

Oh, so for uml_netjig you just link in some more some object files which
do the arp answering, packet injection and so on?  That wasn't clear to
me.  This makes much more sense ...
