Tom, I think it would make sense to allow Name= matches in the [Match]
section of .link files, no? I mean, most of the times .link files are
used to choose the name depending on other fields, but I think in all
cases where the name is chosen at creation time of an interface (like
for example for veth links), it should be Ok to match links based on
the name they already have?
