SLIP problem on Ultrix 3.0

[Shin Yoshimura]

I'm trying to connect two SLIP connections on VAX station II/GPX,
Ultrix 3.0. It has one ethernet interface (qe0). First sl-ip (sl0) is
successfully connected. But second one (sl1) cannot be established.
Packets are incoming, but no packets are outgoing on sl1. Trying to
ping, "Network is down" is backed from /etc/ping.

I tryed to exchange the attached hosts on sl0 and sl1, sl0 is OK, but
sl1 is NG.

Is this any configuration problem or bug of sl driver (if_sl.o) or
other bugs of Ultrix 3.0?
