How do rndis0 and eth0 interfaces get set up?

In a normal installation, looking at ifconfig (or ip) in adb shell, there are no rndis0 or eth0 interfaces set up. Once USB tethering or ethernet tethering is enabled, they show up.

With my GNU/Linux hat on, I thought there is some module loading and udev happening in the background, but clearly, that's not the case.

Can anyone explain what is happening in the background and how can this be replicated via shell commands?

@IrfanLatif got a bit lost in the translation there. I am not sure that applies to Android 11 (AOSP/ArrowOS), for example I can't create a /system/etc/init/custom.rc due to read-only file system. On short term, do you know the quick command to enable ethernet tethering? I found the one for usb (svc usb setFunctions rndis), but I need to use the Android 11 newly introduced ethernet tethering. – Luc Sep 17 '21 at 09:55
Go system-less using something like Magisk modules. // No I'm not aware of quick command. Sorry. – Irfan Latif Sep 17 '21 at 11:10
