[libvirt] libvirt 1.2.16 unable to set link state for ethernet network type

[Vasiliy Tolstov]

I can't set link state for network=ethernet, in older versions all works fine.
As i see in qemu_hotplug.c:
        case VIR_DOMAIN_NET_TYPE_ETHERNET:
            if (STRNEQ_NULLABLE(olddev->data.ethernet.dev,
                                newdev->data.ethernet.dev) ||
                olddev->nips == 0 || newdev->nips == 0 ||
                !virSocketAddrEqual(&olddev->ips[0]->address,
                                    &newdev->ips[0]->address)) {
                needReconnect = true;
            }
        break;

If needReconnect = true, than i get error in libvirt like "Operation
not supported: unable to change config on 'ethernet' network type"

In my case, i don't change device name and i don't have ip addresses
in xml definition. Whats wrong ?
Thanks for help.
