Documentation: networking: switchdev: Update port parent ID section

Update the section about switchdev drivers having to implement a
switchdev_port_attr_get() function to return

commit bccb30254a4a ("net: Get rid of
SWITCHDEV_ATTR_ID_PORT_PARENT_ID").

 Switch ID
 ^^^^^^^^^

-The switchdev driver must implement the switchdev op switchdev_port_attr_get
-for SWITCHDEV_ATTR_ID_PORT_PARENT_ID for each port netdev, returning the same
-physical ID for each port of a switch.  The ID must be unique between switches
-on the same system.  The ID does not need to be unique between switches on
-different systems.
+The switchdev driver must implement the net_device operation
+ndo_get_port_parent_id for each port netdev, returning the same physical ID for
+each port of a switch. The ID must be unique between switches on the same
+system. The ID does not need to be unique between switches on different

 The switch ID is used to locate ports on a switch and to know if aggregated
 ports belong to the same switch.
