Hi,
i have the following card:

[10b5:9050] (rev 01) Subsystem: PLX Technology, Inc. IXXAT CAN i165

lspci -x -d 10b5:9050
07:05.0 Network controller: PLX Technology, Inc. PCI <-> IOBus Bridge
(rev 01)
00: b5 10 50 90 03 00 80 02 01 00 80 02 10 00 00 00
10: 00 50 40 fe 01 a4 00 00 00 00 40 fe 00 00 00 00
20: 00 00 00 00 00 00 00 00 00 00 00 00 b5 10 67 10
30: 00 00 00 00 00 00 00 00 00 00 00 00 0b 01 00 00

It offers an sja1000 can bus. It is a relatively old card. The 10b5:9050
suggested that the driver plx_pci + sja1000 are offering support for it,
but i guess it gets rejected by the subsystem id, but i cant figure out
if i have done it wrong.

from the output of the pci configuration space, i guess the subsystem id
is 1067 so i authored the appended patch. My added printk doesnt get
triggered, so i assume, the pci description is still wrong.

Any hints would be appreciated...

This is exactly the card.
