--------------------------
Intel 82599 NIC VF(or Intel I350 NIC VF) can not work in win7 32bit guest and win8 32bit guest; it can be assigned, but the interface in guest cannot get IP address.

Note:
Intel 82599 NIC PF(Intel I350 NIC PF) can work in guest
Intel 82599 NIC VF(Intel I350 NIC VF) can work in 64bit win7/win8 guest

Reproduce steps:
----------------
1. qemu-system-x86_64 -enable-kvm -m 2048 -smp 2 -device pci-assign,host=0e:10.3 -net none ia32p_win7.img -usbdevice tablet

Current result:
----------------
Intel 82599 NIC VF and Intel I350 NIC VF can not work in 32bit win7 and 32bit win8 guest

Expected result:
----------------
Intel 82599 NIC VF and Intel I350 NIC VF  work in 32bit win7 and 32bit win8 guest
