Shouldn't it better to have common code in PCI subsystem to disable PCIe AER etc,
So that other drivers can be used in future.

Do we need a special PCIe switch for this? Or Generic PCIe switch would do?

Is communication between i40e and ipn3ke proprietary scheme?
Who is the PCIe bus master here? Ipn3ke or i40e?
