This feature bit can be used by hypervisor to indicate virtio_net device to
act as a standby for another device with the same MAC address.

VIRTIO_NET_F_STANDBY is defined as bit 62 as it is a device feature bit.

This is not part of current qemu master (head 6f0c4706b35dead265509115ddbd2a8d1af516c1)
Were I can find the qemu code?

Also, I think it makes sense to push HW (qemu HW in this case) first
and only then the driver.

I had sent qemu patch with a couple of earlier versions of this patchset.
Will include it when i send out v10.
