-description = """Incus recently added support for USB attached network interfaces.
-As with any network device, we generate a MAC address (using our MAC OUI) and allow the user to override that to a value of their choice.
-
-That's when we noticed that no matter what MAC address we set, the resulting MAC always has the prefix swapped to "40:". Looking into the code, this is done on purpose here:
-
-https://gitlab.com/qemu-project/qemu/-/blob/master/hw/usb/dev-network.c?ref_type=heads#L1386
-
-Unfortunately there is no comment in the code or in any of the commits touching that code as far as why that is.
-
-We've also looked at the libvirt code handling those devices and that code seems to also assume that a user provided MAC will be correctly passed through to the guest, no mention of the odd prefix override.
-
-This is a bit concerning as there are valid IEEE OUI with the "40:" prefix.
-So this means that QEMU may be generating collisions with actual physical MAC addresses...
-
-For a few months now, I've been applying this small patch to my own Incus packages (which bundle QEMU) and haven't heard or seen any obvious issue from the change.
-
-https://github.com/zabbly/incus/blob/daily/patches/qemu-0001-usb-net-mac.patch
-
-Does anyone know why this hardcoded MAC address prefix exists?"""
