I need to spin up more on naming under Linux, but I've seen kernel features
for different kinds of names depending on the driver, i.e. predictable vs
unpredictable naming. At least on my Ubuntu 17.10 box, it's renaming the
devices to have long numbers, appears to be based off MAC:

$ ifconfig -a

wlx6466b31999f5: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
Actually it isn't a kernel feature, this is systemd predictable network
interface names feature. Having that is very welcome for network

The background on the systemd page was very helpful, thanks!

There is some kernel side support in netdev, see https://github.com/torvalds/linux/commit/685343fc3ba61a1f6eef361b786601123db16c28
