내 이더넷 어댑터에 두 개의 장치가 있는 이유는 무엇입니까?

내 노트북에는 이더넷 포트와 Realtek 이더넷 컨트롤러가 있습니다.

$ ip -brief addr
lo               UNKNOWN        127.0.0.1/8 ::1/128 
enp2s0f0         DOWN           
enp5s0           UP             192.168.50.83/24 fe80::3af3:abff:fe0c:886f/64 
wlp3s0           UP             192.168.50.127/24 fe80::6dc5:4c36:33c3:2795/64

$ lspci | grep -i ethernet

나를 혼란스럽게 하는 것은 enp2s0f0(아래)과 enp5s0(위)이라는 두 개의 이더넷 장치가 있다는 것입니다. 나는 그 이유를 알아내려고 노력해 왔습니다. 내 추측으로는 이것이 펌웨어 업데이트(rpm의 차이로 인해)의 결과인 것 같지만, 내가 잘 이해하지 못하는 매우 기본적인 것이 있는 것 같습니다.

노트북은 AlmaLinux 9를 실행하는 Thinkpad P14S입니다.

고쳐 쓰다

노트북은 때때로 도킹 스테이션에 연결됩니다. ip addr도크에 연결했을 때의 출력 은 다음과 같습니다 .

enp5s0 is the RJ45 port. enp2s0f0 is the proprietary connector next to the 2nd USB Type-C port for use in the Lenovo ThinkPad Ultra Docking Station or with a Lenovo ThinkPad Ethernet Extension Cable Gen 2 cable.

도크가 USB-C 도크인 것 같습니다.
