--- Comment #8 from Michael Gmelin <grembo@FreeBSD.org> ---
This change could break people's existing automation though. The commit which
added echoing the interface name[0] gives an example of why this was added in
the first place:

    $ ifconfig tap create mtu 9000
    tap0
    $ ifconfig tap create mtu 9000 name blah
    blah

So there is a (small?) potential for a POLA violation.

Even if that's not considered an issue, the one-line change wouldn't cut it, as
it leaves dead code behind.
