Hmm.. on a hunch I'll assume this was meant for the plip thread on
-current ;)

I can set that up yeah, I used plip since I assumed it would be
faster than ppp over serial line. I've been getting at most
~60 KBps.
My only reservation in removing this would be, it came in handy
and still primarily works. It's useful absent any other link but
imposes a large overhead. Should this driver still use splhigh()?
I'll also note that even NetBSD seems to omit plip support at the
moment. So I'll take that as a prophetic nod from the code-reaper.
Funny thing is now I'm having trouble reproducing the IP header
problem.. could it be cable/hardware that was the culprit?
