With this patch as-is, shaping rules are applied only when creating TAP
devices. This mean only network types VIR_DOMAIN_NET_TYPE_NETWORK and
VIR_DOMAIN_NET_TYPE_BRIDGE.
We really need to support VIR_DOMAIN_NET_TYPE_DIRECT (macvtap) as well.
It also uses a tap device.

Huh, I didn't know it is possible to have a pool of devices within one
<network>. So in this case, this patch silently does nothing.
It isn't possible, yet. :-)
