of_node/label instead of
phys_switch_id and don't try to concat
port label by lan + port_id.
Besides that, it will fix discrepancies between
port label on Turris 1.x, in which case they are opposite of each other,
- LAN1 <-> port 4 <-> lan5
- LAN5 <-> port 0 <-> lan1
Note: Refactoring of code for Mox and Omnia is intentionally postponed, because detection and reporting interfaces hasn't changed for quite a long time and the current state is considered as expected behavior -at least from user point of view ;-)
