ifconfig -a is showing br-ba165999130f instead of eth0 (ethernet works)

I have my PC connected to the router using a cable and I also connected a WIFI USB TP-LINK.

Just checking ifconfig -a and I noticed there is no eth0 interface. Instead, the first one is called br-ba165999130f and I think it's the eth0 (no matter if I pull out the WIFI USB).

What's the reason behind it?
