Modern linux such as Debian, Ubuntu etc no longer uses interface names like eth0. This replacement find_mac() backported from UxPlay 1.42 robustly finds the mac_address of the first active network port on linux systems, as well as on *BSD and macOS systems. (i.e, all unix-like systems but not Windows)

Looks got to me. Thanks for the backport!
