I would like to see a clean solution to setting up a bridge.
There was a patch that was never completed to allow migrating a ethernet
interface into a bridge. It is possible to do it with a script, by
dumping routes with ip command and replaying that into the bridge.
To really do it right (including neighbor table and iptables rules)
would be complex, especially considering the error cases.
Having looked at the FreeBSD code, that is not the answer. Trying to keep
a clean separation between IP and bridging is much better.
