sundance driver problem detecting DFE-550 card

[Georg Wittenburg]

Greetings.

I contacted Donald Becker (mainainer of sundance driver according to the 
comments) about this issue who told me that he wasn't in charge of the 2.4 
driver anymore and suggested to ask on the list.

My vanilla Linux 2.4.2 system has some trouble using the D-Link DFE-550TX
network adapter with the sundance driver that should support that card
according to the docs .

Until now I've used the dlh5x driver right from the D-Link homepage, but that
doesn't compile with Linux 2.4 and seems to be rather unsupported.

The symptoms are: sundance.c compiles to a module and is loaded over the
normal init scripts without problems. However asking for a "ping 192.168.1.1"
(our local server) doesn't yield anything (switching back to the old 2.2.17
kernel and dlh5x works). Furthermore, the ifconfig statistics remain empty
and also ifconfig reports a different base address than when using the old 
dlh5x driver. Also note the different memory addresses reported in /proc/pci.

I've gathered the following info which I hope will help track down the
problem:

ifconfig under 2.4.2 and sundance:

eth0      Link encap:Ethernet  HWaddr 00:50:BA:0F:5E:DD
          inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0

          Interrupt:5 Base address:0xf000

/proc/pci under 2.4.2 and sundance:

      Non-prefetchable 32 bit memory at 0xd4800000 [0xd480007f].

ifconfig under 2.2.17 and dlh5x:

/proc/pci under 2.2.17and dlh5x:

More (lengthy) output of Donald Becker's debugging tool (alta-diag) is 
available.
