Hi all, Based on discussion with Ido and feedback from Jakub there are clearly two classes of users that implement SWITCHDEV_ATTR_ID_PORT_PARENT_ID: - PF/VF drivers which typically only implement return the port's parent ID, yet have to implement switchdev_port_attr_get() just for that - Ethernet switch drivers: mlxsw, ocelot, DSA, etc. which implement more attributes which we want to be able to eventually veto in the context of the caller, thus making them candidates for using a blocking notifier chain Changes in v2: - resolved build failures spotted by kbuild test robot - added helpers functions into the core network device layer: dev_get_port_parent_id() and netdev_port_same_parent_id(); - added support for recursion to lower devices Changes from RFC: - introduce a ndo_get_port_parent_id() and convert all relevant drivers to use it - get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID A subsequent set of patches will convert switchdev_port_attr_set() to use a blocking notifier call, and still get rid of switchdev_port_attr_get() altogether.
