The device bus LAN ID was obtained from PCI_FUNC(), but when a PF port is passthrough to a virtual machine, the function number may not match the actual port index on the device. This could cause the driver to perform operations such as LAN reset on the wrong port.
Fix this by reading the LAN ID from port status register.

Hi Jiawen Wu,
I am wondering if these devises also support port swapping (maybe LAN Function Select bit of FACTPS). And if so, does it need to be taken into account here?
Does not support yet, thanks. :)
