The switchdev driver can know a particular port's position in the topology by monitoring NETDEV_CHANGEUPPER notifications. For example, a port moved into a -bond will see it's upper master change. If that bond is moved into a bridge, +bond will see its upper master change. If that bond is moved into a bridge, the bond's upper master will change. And so on. The driver will track such movements to know what position a port is in in the overall topology by registering for netdevice events and acting on NETDEV_CHANGEUPPER. |
