The journal records the network state of the host and each change of
that state. The support team reads one file to see the interfaces, the
routes, the resolvers, and the recoveries around an incident. The same
file shows the health of the query path. A change that touches only
AirDrop or virtual interfaces runs no DNS work.

Since these are the interfaces that ctrld will manipulate anyway.
While at it, also skipping non-working devices on MacOS, by checking
if the device is present in network service order
