The differences in netgraph between stable and current are rather big, so
this wouldn't be an easy task, I fear.

What exactly does it do? Yes, I had a look some time ago, but because I
have rather specific needs (a native ATM API and an signalling stack that
can easily be modified) a decided to go a different way.

Well, you need my code and -current for this.

No, this is not HARP...

Hmm. I have no eni driver for that thing. If I get spare time (hear, hear)
I could try to make the hooks into the en driver.
