kvm.git + qemu-kvm.git = result
f4d1f417 + df44afac = bad
eb9ede96 + df44afac = good
But I don't know which exact patch fixed this bug.

Bug detailed description:
--------------------------
Using qemu and kvm upstream, VT-D NIC and SR-IOV VF don't work in Windows
guest. I tried Windows XP, Vista, Win7, Win2k8 as a guest. And I used 82572
NIC and 82576 Virtual Function to assign to windows guest, and got the same
result.
Reproduce steps:
----------------
1.start a Windows guest with a NIC assigned:
qemu-system-x86_64 -m 1024 -smp 2 -device pci-assign,host=08:00.0 -net none
-hda Windows.img
2.check network in the Windows guest. (You'll find the assigned NIC doesn't
work in guest.)
Current result:
----------------
NIC doesn't work in Windows guest
Expected result:
----------------
NIC will work.
