It appears the regression is here: * Set MAC based name for USB network interfaces only for universally administered (i. e. stable) MACs, not for locally administered (i. e. randomly generated) ones. Drop /lib/systemd/network/90-mac-for-usb.link (as link files don't currently support globs for MACAddress=) and replace with an udev rule in /lib/udev/rules.d/73-special-net-names.rules. (Closes: #812575, LP: #1574483) As Raspberry Pi's use eth0 via USB, this breaks running systems.

SRU TEST CASE ============= * Boot with "net.ifnames=0" on the kernel command line, and connect an USB ethernet device. It will still be called enxDEADBEEF with current xenial. With the -proposed version it will instead keep the kernel name, like "usb0" as intended. * Do "sudo ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules" (the other documented way to disable ifnames) and do the above connect/name check test again.
