Description
In 8346 we discovered that we discovered that the the SES phy information always reports the WWN of the SATA Tunneling Protocol bridge ports. As such, for the topology to be understood by the rest of the system, we need to set the bridge-port property for this. This property came in as part of the SM-HBA work and is already used by topo and pmcs.
One thing to keep in mind is that this WWN is usually related to the physical location the device is plugged into, effectively which phy or slot it's plugged into. As such, we need to make sure that when a device has any kind of DR information, that we update this property.
