Since vge(4) failed to detect correct link state you just see ENOBUFS.

This should be fixed in vge(4).

Maybe the next thing is try to fix bugs in vge(4). But I guess it
would take very long time as it needs more clean up.
I also have a old vge(4) hardware that exhibits the same issue you've
seen. I guess I wrote very minimal patch to make it detect link state
but can't find it. I'll let you know if I find that old patch in my box.
