[Impact]
Systems may have NICs attached to the "platform" bus. These are NICs that are onboard, but not attached to a PCI(-like) bus. Rather, they are described by firmware directly. None of the naming policies enabled by Ubuntu by default matches these NICs, so they end up having unpredictable names. In the case where other NICs are attached (e.g. PCIe cards), the ethN enumeration race occurs, making it impossible to have an interface name that is persistent across reboots. That is, if you do a network install over "eth0", on reboot that NIC now maybe "eth3", which causes it to fail to start the network on boot.

The HiSilicon D05 boards are an example of this. It has 4 onboard NICs that are described by ACPI directly, and may also have other PCIe NICs plugged in.

[Test Case]
Boot a system with the characteristics described above, and check to see if any "ethN" interfaces exist.

[Regression Risk]
TBD - depends on the proposed solution.
