The wording of ifconfig DIAGNOSTICS can possibly baffle
a non-native speaker (such as me) with
Messages indicating the specified interface does not exist,
namely, only after parsing the (non)sentence does one realize
that the diagnostics consists of messages indicating THAT
the interface does not exist etc.
As the paragraph does not list the messages (surely there are many),
this really boils down to mentioning that ifconfig does indeed have
diagnostic messages.
I believe nothing would be lost
if this paragraph was deleted.
