Hi,

Bridge port isolation flag (BR_ISOLATED) was added in commit
7d850abd5f4e. But switchdev does not offload it currently.
It should be easy to implement in drivers, just like bridge offload
but prevent isolated ports to communicate with each other.

Your thoughts?

It maps well on Broadcom switches but there was not a known use case 
AFAICT that warranted mapping this flag to program the switch hardware 
accordingly.
