Hi Vivien
Is one notifier per event sufficient?
I've not looked at what actually needs to happen when a port joins a
bridge, in a D in DSA setup. Do we need to both enable the flow of
frames around the switch fabric, but also block those frames going out
ports they should not? Do we need a first notifier to put in place
the blocks, and then a second notifier to enable the flow of packets?
What we don't want is a window of time during the fabric setup as a
whole is inconsistent, and frames a leaking out ports they should not.
