- The number of lanes, which is a quite generic property that allows
   differentating between multiple similar technologies such as BaseT1
   and "regular" BaseT (which usually means BaseT4).

+            mdi {
+                connector-0 {
+                    lanes = <2>;
+                    media = "BaseT";

This is correct when the port is Fast Ethernet. However, as you point
out, now a days, the more normal case is 1G, with 4 lanes for BaseT.
To avoid developers just copy/pasting without engaging brain, maybe
add a comment about it being a Fast Ethernet port?
