Debian version: 10.7.0
Problem: Ethernet interface doesn't show up on ip link or ifconfig.
Possibly useful outputs:

Updated and upgraded all packages
Installed all 3 firmware-linux packages
Installed the firmware-realtek package
Rebooted multiple times
Maybe a couple other smaller things that I don't remember
Other notes:
Wifi works well with wpa_supplicant and dhcpcd and the wlan interface shows up just fine
As of posting, I have been trying to solve this for just more than 3 hours and I have to go to sleep, but if I forgot something important, I'll add it in the morning.
