Thanks, that was it!

I must have missed the note in the docs on that, because with ipv4 I just
had the same subnet, but with ipv6 I don't have a public address assigned
on the bird side. `multihop 1` Fixed the negotiation issue. I got a few
more, but those seem to be related to either gobgp sending malformed
updates (Invalid NEXT_HOP attribute - mismatched address family
(2a01:xx:yy:zz:4746:92e9:327c:d930 for ipv4)), or the bird configuration
not being able to parse a `-` in the interface name. Both unrelated to this
particular issue at hand.
