I really don't know.  Here's also /etc/udev/rules.d/70-persistent-net.rules:

# PCI device 0x1039:0x0900 (sis900)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:03:0d:33:02:17", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# USB device 0x:0x (r8188eu)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="14:cc:20:11:82:ec", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

Help appreciated.
