Erm... They were there on the other devices, but I deleted the lines

It's a link-local address, they're automatically configured for every
interface at "ifconfig up".

At the moment I'm trying to understand what happens after netif_rx() in
the upper layers in linux... I hope to find the problem (or at least
the solution) there. The packets do arrive in the upper layers correctly,
else tcpdump would not be able to see them, but then something seems to
hinder them from arriving at the bridge.
