Diagrams of packet flow through the kernel would help, even if that means a man page with ASCII art.

I don't think a man page is the best place for that really... and such things already exist in documentation elsewhere:

That just kills my net connection. Note that I never
told my host machine to route via the bridge device.
As far as I'm concerned, it ought to still be using eth0.

But the ebtables rules don't just apply to the bridge. They will most likely be applied to the rest of your traffic too. If you want to confine them to that bridge, say so using using --logical-in & --logical-out or whatever.
