Ido Schimmel bcdfd9fb10 bridge: Add missing READ_ONCE() annotations around FDB destination port 
When roaming, the FDB destination port can change without holding the
bridge's hash lock. Therefore, add missing READ_ONCE() annotations in
both RCU readers and readers that hold the lock. In the latter case, the
annotation is not needed in places where the FDB entry was already
validated to be a local entry since such entries cannot roam.
