`Device`'s `desc` is `None` but Wireshark shows it

I believe there may be some issue with how the Device's desc field is retrieved.

On Windows, it works for all the adapters.
On Linux, it works just for some.
On macOS in particular, it's None for all the interfaces even if Wireshark is correctly showing descriptions like:

• "Wi-Fi"
• "Loopback"
• "Thunderbolt 1"

Also Wireshark seems to miss many devices' descriptions, but some are shown.

Aren't you and Wireshark calling the same underlying libpcap methods?

You can just execute networksetup -listallhardwareports on mac to get the hardware type.

On linux any adapter that is wireless starts with wl when you do ip link.

Yep, was just trying to let the pcap maintainers know their library is probably not working as expected to see if they can fix to avoid relying on other tools 👍
