jme driver: MAC spoofing issue

Hi,

I was directed to post the following issue to this list. I apologize if this is not the right place for it.

I have a laptop with an onboard JMicron ethernet controller. Relevant hwinfo output along with additional system information are included at the end of the message.

I am able to change the MAC address using macchanger, ip and ifconfig but I am unable to obtain an IP address via DHCP (using dhcpcd or dhclient) after doing so.

Aside from MAC spoofing, everything else works as expected.

I have posted more information in a thread on the Arch Linux forum [1]. I have also packaged [2] and tested the upstream Git version of the driver [3], but the issue persists.

Does anyone have any idea of how to resolve this? I have looked at the source code but I do not know anything about network drivers. I hope that the solution will be readily apparent to someone who is much more familiar with the code and drivers in general.

Any help would be appreciated.

Best regards,
Xyne
