[linux-tr] Multiple Token Ring Cards

[glynns@us.ibm.com]

All,
Hope you can help me, Ive checked out the Howto, but Im having lots of
difficulty getting two token ring cards in my linux box to work together.

Kernel Version is 2.2.7 and the las mod in the ibmtr.c file is 10 Mar 1999 so,
Im pretty sure I have the latest.
The IBM Cards have dip switches, and I have set one to primary and the other to
secondary.

I can manage to get the kernel to recognise both tr0 and tr1, however, only 1
token ring will Insert into a ring.
When I try and ifconfig tr1 it hangs, and doesnt seem to attempt to insert.

Both Cards are the IBM 16/4 ISA cards with dip switches.
The rings are physically different rings on different MAU's.

I have tried multiple Cards, and the best I can do even with 2 different cards
in the box is to get 1 to insert and the other to be recognised, but no insert.

ibmtr.c: v1.3.57   8/ 7/94 Peter De Schrijver and Mark Swanson

tr0: ISA 16/4 Adapter/A (short) | 16/4 ISA-16 Adapter found

tr0: Hardware address : 08:00:5A:49:5A:FA

mpnserv:~# ifconfig tr1

When I try a:

mpnserv:~# ifconfig tr0 10.10.10.1 netmask 255.0.0.0

tr0 never inserts, (tr1 is the primary), and the command hangs (although the box
 doesnt hang).

Again, this happens with multiple cards.

Thanks In advance for any suggestions.
