Thanx makes more sense, but I have noticed something weired if you can
shade some light on.

I added printfs one when the module is first loaded (static int
event_handler(module_t module, int event, void *arg)):

Try to load it from laoder on boot; I think that should work as we are
setting the curvent for the kernel startup.

The problem you are seeing is a bug in the current implementation that
you cannot add any physical network interface after the kernel started.
This applies to cardbus/usb/... as well as any kind of ethernet
interface, so a kldload igb should yield it as well.

The fix for that is easy and hard at the same time:
A) either touch all drivers
B) or touch all cloned interfaces and change 3 common lines.
   or try to make cloners aware of vimages.

Solution B) is sitting in perforce with the entire stuff that it depends
on and was started with CH=179022,179255 but not limited to that if you
want to have a peek.

What you certainly can do locally to your driver for now is to make a
change like this:

+#ifdef VIMAGE
+       CURVNET_SET(vnet0);
        ifp = if_alloc(IFT_ETHER);
+#ifdef VIMAGE

It's the type A) kind of change from above that will break eventually
in the future.
