What are the strange network interface names in linux?

Question

linux

Hello.
Help me figure out where the legs grow from :)
I recently purchased a Raspberry Pi and finally began to delve into the study of linux.
And immediately ran into this problem.
If you connect only the local network, then the eth0 interface appears in the system. Everything is as it should be. I also connect a wifi adapter and get the following interface names in the system
: enxb827eb80a896
wlxaca213d5dd06.
instead
of eth0 and wlan0.
I googled this question and found that udev is responsible for this and they say you can configure it manually and bind the necessary names to mac addresses. So I did it and it seemed to work.
But why did it suddenly start working? Previously, how many laptops played with different linux distributions, everything was always fine. What is happening now? From my manipulations under Raspberry - I removed the GUI autorun and hung up a static IP on eth0.
Thanks :)

Add the line net.ifnames=0 to the kernel startup parameters, the
problem comes from here: https://www.freedesktop.org/wiki/Software/systemd/...
