So this may be a bit of a dumb question since I don’t know enough to know if I am wrong but can the old eth0 not hang off the bridge? I mean, your explanation that whereas before the BMC thought of itself hanging off a switch, now the BMC considers the switch to be a part of itself makes perfect sense. I guess I am asking can the BMC think of itself “owning” the switch but it also thinks of itself hanging off that switch as a 7th interface in the same way that the other 6 interfaces (4xnodes + 2xphysical) do?
