As Stephen reported earlier, VMware PCI emulation of interrupts is somehow broken, so INTX mode is not supported (see http://dpdk.org/ml/archives/dev/2014-May/002432.html). The current code makes VMware e1000 unbindable to igb_uio driver and throwing -EIO error. What I suggest is to throw a kernel warning but make the work with this kind of NIC possible.
