-From: Dominique Martinet <dominique.martinet@atmark-techno.com>
-
-The previous commit assumed that local addresses always came from the
-kernel, but some devices hand out local mac addresses so we ended up
-with point-to-point devices with a mac set by the driver, renaming to
-eth%d when they used to be named usb%d.
-
-Userspace should not rely on device name, but for the sake of stability
-restore the local mac address check portion of the naming exception:
-point to point devices which either have no mac set by the driver or
-have a local mac handed out by the driver will keep the usb%d name.
-
-Fixes: 8a7d12d674ac ("net: usb: usbnet: fix name regression")
