This was fixed in http://anonscm.debian.org/cgit/pkg-
systemd/systemd.git/commit/?id=b3e7c6ee, thus is fixed in yakkety. I'll
backport the fix to xenial.

Title:
  systemd 229-4ubuntu6 ignores net.ifnames=0 on USB

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Xenial:
  New
Status in systemd package in Debian:
  Unknown

Bug description:
  Description:    Ubuntu 16.04 LTS
  Release:        16.04

  The upgrade to systemd/udev 229-4ubuntu6 breaks net.ifnames=0 for USB
  devices.

  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.

  Before:
  ii  systemd        229-4ubuntu4 armhf        system and service manager
  ii  udev           229-4ubuntu4 armhf        /dev/ and hotplug management daem

  3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
      link/ether b8:27:eb:16:39:e9 brd ff:ff:ff:ff:ff:ff

  After:

  ii  systemd                      229-4ubuntu6        armhf               system and service manager
  ii  udev                         229-4ubuntu6        armhf               /dev/ and hotplug management daemon

  With the default interfaces configuration, all networking is lost on reboot after upgrade.
