Hi，

after testing your patch,the guest will send arp packet when it
configure vlan or alias on the virtio net.

But bridge or bond do not send arp. what's your opinion?

BTW,this feature need modify the driver of virtio net.

Only the newest linux kernel support it. So what's about old guest os?

Thanks.
