 Predictable interface names is enabled by default on systems using {{{systemd}}}/{{{udev}}} however you can disable it in a couple of ways:
- * pass in a kernel command-line parameter of {{{net.ifnames=0}}}. Note that this is 'not' a kernel feature (thus is independent of what kernel version you are using) but the {{{systemd}}}/{{{udev}}} components that implement this feature look for that on the command-line.
- * remove {{{/lib/systemd/network/99-default.link}}} from the root filesystem.

 Alternatively you can also create your own {{{link}}} files to name interfaces to your liking. A {{{link}}} file defines matching criteria and link criteria for naming. You can use 'udevadm info <device>' to obtain details that {{{udev}}} knows about devices (ie 'udevadm info /sys/class/net/eth0' or /udevadm info /dev/ttyUSB0'). Your link files should be placed in {{{/etc/systemd/network}}} and should sort before {{{99-default.link}}} from {{{/lib/systemd/network}}}.

+An example to force a wlan0 name by MAC address c0:ee:40:99:
+{{{
+root@gw7301:/lib/systemd/network# cat 90-wlan0.link
+[Match]
+MACAddress=c0:ee:40:99
+
+[Link]
+Name=wlan0
