Expected behavior

Enumerate all interfaces when asked for also "disabled" ones (aka upOnly = false)
Poco::Net::NetworkInterface::list(false, false)

I played with the first argument just to see if that might have an impact.

In my scenario I don't get my eth1 and my wlan0.
Same behavior on another system too.

Actual behavior

Enumerates only the active interfaces
