So, you claim in the commit message that it's about a hotplug event, but
the only events are the bridge being attached and detached, so not a
hotplug event?

And why a bridge would want to be notified that itself (or another?)
bridge is being attached or detached?

You need documentation, and a more descriptive commit message.
