Feature: determining lan port a device is connected to

[ghmon]

Environment:

fritzconnection v1.14.0
FRITZ!Box 7580 at http://169.254.1.1
FRITZ!OS: 7.30
Ubuntu 22.04 LTS
Python 3.10.12

In the user interface of the fritzbox the Lan ports a device is connected to is displayed (e.g. "LAN 1"). Maybe i am overlooking this, but can't figure out how to get that port number.
