ip: Allow for easier debug of buggy devices that dont send their names

With the old message couldnt tell which device had the bug.
This patch provides at least an ifindex to narrow it down.
Theres also no point in bailing out because of one bug; we
allow it to go on so we could dump as much info as we can
