?Actually, it is configured as a regular `device':

?(`vector deintr' really belongs elsewhere, but this is a completely
?different topic).  The argument against a /dev entry begins with
?`what would you do with it?'

Why, open it for starters. Then you could ioctl instead of
bind, listen, accept and connect, [gs]etsockopt.

When NBS first went to networking, someone was having problems
with one of their VAXen. I volunteered to help, and after
I tried 'ifconfig ex0' (they had an il), I spent quite a bit
of time looking for it in /dev. I then logged onto all the
other (three) systems that were up and running and started
looking for stuff there too. What a dirty trick!
