Title:
  73-special-net-names.rules is renaming manually created wifi interface

Status in systemd package in Ubuntu:
  New

Bug description:
  The 73-special-net-names.rules file from 229-4ubuntu5 is renaming USB
  wifi network interfaces that I create manually with "iw phy phy0
  interface add wifi0 type managed":

  # Use MAC based names for network interfaces which are directly or indirectly
  # on USB and have an universally administered (stable) MAC address (second bit
  # is 0).
  ACTION=="add", SUBSYSTEM=="net", SUBSYSTEMS=="usb", NAME=="", ATTR{address}=="?[014589cd]:*", IMPORT{builtin}="net_id", NAME="$env{ID_NET_NAME_MAC}"

  
  The device is being renamed by udev as soon as it is created:
