Without this patch (0.12.3) I get the following error message when
trying to pass 2 functions of an ixgbe adapter to the guest:

falla:/abuild/agraf/qemu-kvm/:[0]# qemu-kvm -pcidevice host=07:00.0
-pcidevice host=07:00.1 -nographic -append console=ttyS0 -kernel
/boot/vmlinuz.x -initrd /boot/initrd.x
device: 07:00.0: driver="pci-assign" host="07:00.0"
device: 07:00.1: driver="pci-assign" host="07:00.1"
rom: requested regions overlap (rom 07:00.1. free=0x000000000000ac00,
addr=0x0000000000000000)
rom loading failed


The same code works with qemu-kvm.git. Cherry picking this commit
(51c0dad5ce383be94ca7c46e491ada17cc9ec416) also makes it work in
0.12-stable.


Thus I'd incline we also take this patch into 0.12-stable.
