Till kernel 5.7 PF and VF representors are exposed as virtual device. They are not linked to its parent PCI device like how uplink representor is linked. Starting from kernel 5.8 due to new change [1] the PF and VF representors are linked to their parent PCI device, and so "get_ifname_by_pci_address" fails to get the correct UpLink Representor. This patch modifys the behviour of "get_ifname_by_pci_address" to check the physical port name of the netdev in vf_pci_addr_path/physfn/net to match the formart for the uplink "p\d+".
