Fwiw, it's not really wrong, one is the name in /e/n/i and the others
are interface names per `ip link`, but it naturally can be a bit
confusing as is.
Depends also a bit on what we want, i.e., it probably makes sense to always
show the name used in the /e/n/i config in the name column, and always filter
that out from the alternative names displayed, as that allows the easiest
correlation to the /e/n/i config, which is the main source of true for this
panel.
The small downside for that is then that the Alternative Names column is not
a 1:1 mapping of what `ip link` shows as altname, but that probably is not
an actual issue, after all they all live in the same namespace and are
interchangeable for usage with the iproute2 tools.
But that might also mean that we have to treat duplicates explicitly here
in the API call enhancing that info. Waiting until tomorrow makes sense in
any way though, as Stefan will be back from his short vacation then and
might have some input here.
