No, Name= matches only work in .network units, not in .link units. A
link unit without any valid match option matches any interface though;
so if you have a .link unit with Name=dummy0 in its [Match] section, it
will actually be applied to dummy0... but also to all other interfaces,
which can be very confusing.
