Summary: /proc/net/devices doesnt show all devices using cat. With dd all are
available.
I tested a kernels prior to
http://linus.bkbits.net:8080/linux-2.5/cset@1.797.156.3
and it doesnt seem to have this problem.
If I do a
& cat /proc/net/dev
Inter-| Receive | Transmit

I get net devices till eth1, but eth2 and hsi0 are available nevertheless.

I haven't tried to make that many net devices.
Acme, does this look helpful?
Christian, can you test this patch?

Oh well, I don't think that works.
How do I configure the dummy network driver to get loads of interfaces?

Just copy the dummy.o to dummy1.o dummy2.o dummy3.o, insmod and ifconfig
them.

You didn't need to. I had already seen the same results that you saw.

Doesn't work for me. insmod (from ver. 0.9.11a module-init-tools)
won't load multiple copies of dummy[n].o or dummy[n].ko.
(with dummy already loaded)
For the .o files, it says:
dummy: no version magic, tainting kernel.
Error inserting 'dummy1.o': -1 File exists
and for the .ko files, it says:
Error inserting 'dummy1.ko': -1 File exists

Well, it fails differently. Now i get all devices but several times.

Weird one to me. Maybe someone else knows...
You were doing this test in an X terminal window, right?
and not on a text-only console?
The reason that I say that is that I can reproduce this problem on
2.5.68, but only in an xterm or similar window, but when I switch back
to a console, the entire device list is displayed.
???
