This setting(bridge.forward-delay) in the bridge connection affects the time
spent in LISTENING and LEARNING state. You can run the follwing command to
reduce it to minimum value allowed.

> nmcli connection modify your-bridge-connection-name bridge.forward-delay 2

I'm closing this bug as RESOLVED INVALID, as this is more of a setting issue
than a bug.

Thanks for report.
