Hello!
Is it possible to bridge ip tunnels (IPv6 in IPv4)? brctl gives me an
error "Invalid argument",
and from strace it seems it misses some ioctls from kernel...
any ideas?
I need it to be able to give my UMLs a public ipv6 address.

Uhm. The only things you can bridge together are ethernet devices.
An IP tunnel is not an ethernet device, is it? This requirement is
there because the bridge just fowards ethernet frames, and knows
nothing about doing neighbour resolution (ARP) to get the right MAC
address, etc.
You might want to fiddle something with proxy ARP.

That is because the bridge code works at the Ethernet level.
It is an 802 Ethernet bridge, not an IP tunnel.
