Hello guys,
I made 3rd attempt to enable the ability to initialize r8169's MAC address
on initialization. The proposed patch below works for all my Realtek devices,
but you had some issues with the previous one. Could you please test it on your
devices? I would like to close finally this long term issue.
Thanks,
Ivan
