network interface names

Hello there,

I was looking for some network settings on my MacBook and I am a little bit confused: When I do a

$ ifconfig

in a terminal, I get an output for the following devices which I tried to assign to the physical devices:

- en0 -> wifi

- en1 -> ???

- en2 -> network cable

- p2p0 -> ???

- awdl0 -> ???

- bridge -> ???

Now, I wonder if anyone could help me to identify the physical devices behind the ones with ???.
