From: Shmulik Ladkani <shmulik.ladk...@ravellosystems.com>
Following the previous patch which changed vmxnet3 to be a pci express
device, this patch introduces a boolean property 'x-disable-pcie' whose
default is false.
Setting 'x-disable-pcie' to 'on' preserves the old 'pci device' (non
express) behavior. This allows migration to older versions.
