| |
Hello,
Recently we've got some computers with new motherboard having NVidia chipset. The motherboard has nforce12 & nforce13 Ethernet cards. I've noticed that MAC address is setup random each boot. I debugged the driver and found that these cards have right-byte order of MAC address but the driver is expecting incorrect byte-order for these models. I made hardcode the driver and MAC address became valid. Also I tried to understand that difference in this revision of the chipset. But I couldn't find anything interesting. I'm ready continue the investigation to do correct changes in the driver but I need an advice.
P.S. It's simple to add DEV_HAS_CORRECT_MACADDR to pci_device_tlb for these types of Ethernet. But I think it's not right decision because it would break older revisions of these models.
