Per-port sounds better than per-bridge. And I will make it enabled by
default.

IMHO the default should be off.  Suddenly losing your subscription
because someone else on the same port unsubscribed is a lot more
annoying than getting a few minutes of unwanted multicast data.

You are right, this is why it should only be used when there is one
client behind the port.

Thanks!
