ndis wrapper around dwl-520 rev E

[lreid at a.cs.okstate.edu]

Hello everybody,

I'm starting fresh with FreeBSD 5 after my 4_STABLE system's disk ate
itself, and I've been fighting with wireless adapters for a little
while. I'm wondering if anyone can help me make some sense of this
problem:

The machine has inside it a DLink DWL-520 card. It's a revision E, so it
is not supported by wi (although wi will try to init and fail). Now that
I am running FreeBSD 5.3, I've decided to give the ndisulator a shot. I
had a hunch that having both ndis and wi vying for control of the device
would be a badthing, so I recompiled my kernel _without_ device wi.

I used the WinXP inf and sys files on the DLink install CD to make the
ndis_driver_info.h. (note: the inf file gave me grief until I read
somewhere that it needed a newline at the bottom to work correctly) I
compiled if_ndis.ko and kldload'ed it. pciconf -l shows:

The ndis driver seems to have initialized on pci0:10:0, but no ndis
adapter shows in ifconfig -a. Troubled by this, I moved the driver
object into /boot/kernel and added load_if_ndis="YES" to loader.conf,
and rebooted. Maybe dmesg would tell me something important. It did:

ndis0: <D-Link Air DWL-520 Wireless PCI Adapter(rev.E)> mem
0xd7000000-0xd7000fff irq 5 at device 10.0 on pci0
can't re-use a leaf (BusType)!
ndis0: NDIS API version: 5.1
ndis0: NDIS ERROR: c0001394 (unknown error)
ndis0: NDIS NUMERRORS: 0
ndis0: init handler failed
device_attach: ndis0 attach returned 6

So that's where I am. I don't know what to make of this dmesg output.
Can anyone offer some insight?

Thanks,
Reid
