Currently we listen to netdev register/unregister event based on PCI device. When in switchdev mode PF and representors share the same PCI device, so in order to pair ib device and netdev in switchdev mode compare the netdev that triggered the event to that of the representor. Expose a function that lets you receive the netdev associated what a given representor.
