> This patch adds support for switchdev ops on the VF Port representors and
> the PF uplink, the only operation implemented is the port attribute API to get
> the port parent ID or the switch ID. The switch ID is used to identify the
> net_devices attached to the same HW switch.
> 
> The switch ID returned for the VF Port representors and the PF uplink is the
