I think set_ethernet_addr() shouldn't be called at reset-resume.
The MAC address should be restored to the current one, not the
default value. Someone may change the MAC address before suspending.
And the MAC address would become the default value after reset-resume,
if set_ethernet_addr() is called.

Best Regards,
Hayes
