The core USB driver message.c is missing get/set address functionality
that stops ifconfig from being able to push MAC addresses out to USB
based ethernet devices.  Without this functionality, some USB devices
stop responding to ethernet packets when using ifconfig to change MAC
addresses.

Hi Charles

ifconfig has been deprecated for years, maybe a decade. Please
reference the current tools, iproute2.

Thank you.  I would, but that is not available on the system under test, while ifconfig is.
